1. I recently acquired a Gibson Lap steel. The problem is, I know nothing about lap steels. Could someone help me identify the date and model? Serial # 1114-2 Thanks, -Jeff.
2. GIBSON SKYLARK LAP STEEL – 1957.SOLD! SERIAL NUMBER: 185541 DATE: 1957 It may have been the Art Deco period, but whoever designed this unique Hawaiian instrument either had a fantastic imagination or adventurous taste, considering this is circa late ‘50’s! Either way, this is a collectors dream!

Gibson guitar serial numbers are, like a lot of serial number systems from guitar manufacturers, a complicated beast.

But with a little bit of research you should be able to find out when your Gibson was built and in some cases where.

There are a number of distinct time periods for Gibson’s serial numbers, where the systems differed. There are also other ways of determining the age of your instrument, including FON’s and things such as logo designs.

FON’s

In addition to serial numbers older Gibson guitars also had Factory Order Numbers (FONs) imprinted. In some cases, in fact, only FONs were used and there was no serial number (this was mainly for early low-end models).

FON’s (and serial numbers) on Gibson guitars are usually found either on the inside of the back of the guitar (inside the sound hole) or on the back of the headstock).

FON’s were used from 1902 to 1961.

Other Identifiers

There are some other ways you can get an idea of the age of your Gibson.

Logo

Gibson’s logo has been largely unchanged since 1947 but before that time the logo changed a bit, so you can use that to help identify the era your guitar was built.

Made in USA

From 1970 onwards a “Made in U.S.A” was engraved below the serial number. This can help determine if your guitar was from the 1960s or 1970s (some guitars during those 2 decades had the same serial number).

Other Features

You can also use other features to help identify the time period of your instrument. Some of these include:

• Volutes: Extra bits of wood carved into the headstock where it meets the neck. These were starting to be added in 1969 – so if your instrument didn’t have them then it’s likely to be pre-1969
• Things such as tuners, capstans, plates can also give you clues – though remember that an older instrument could have had these items replaced so it’s not a definite clue.

Serial Numbers

O.k. so why discuss all these other aspects, when this post is supposed to be about serial numbers!

Good question – and the answer is simply that the serial number system used up until 1977 wasn’t the easiest or most reliable system – so you may not be able to accurately determine anything about your guitar using the serial number alone.

O.k., let’s take a look at the different time periods of serial numbers from Gibson Guitars.

1902-1947

The following serial numbers apply just to acoustic guitars.

During this period, the system was actually relatively simple. Guitars were just given the next available number.

The chart below shows the year that relates to the serial number. The serial numbers shown represent the approximate last serial number for that year. The first serial number for acoustic guitars was 100.

1947 to 1961

Once the serial numbers hit 99999, Gibson decided to change to a new system, rather than go into 6 digits.

The new system used a letter to prefix the numbers. The first guitar in this new system was A 100 which was in April of 1947.

1961 to 1970

A new system, introduced in 1961, was made to cover all of the instruments in Gibson’s line (not just acoustic guitars). This was pretty poorly done though (IMO) and meant that some serial numbers were reused so a certain serial number could be from a guitar from different years.

1970 to 1975

It didn’t get any less confusing during this time either. The biggest telling factors for guitars from this period, as opposed to the guitars from 1961 to 1969 is the “Made in U.S.A” that can be found on guitars from 1970 onwards.

6 Digit Serial numbers were still used so a lot of the same numbers were also used on 1960s models. To make matters even more confusing, there wasn’t really an order for these serial numbers – so you could have something from 1975 that started with a 1 and something from 1972 that started with a 9.

Gibson Skylark Lap Steel

Some serial numbers also used a letter (just because?)

1975 to 1977

Thing get a little simpler. These serial numbers started with either “96” “00” or “06” with the 96 representing 1975, the 00 representing 1976 and 06 representing 1977. Not sure why these numbers were used, but at least it was uniform!

1977 to Present

Finally, in 1977 a much more logical serial number system was introduced.

This is an 8 digit system and follows the format YDDDYPPP.

• The YY represent the year the guitar was made
• The DDD is the day of the year that the guitar was made
• The PPP represents the factory the guitar was made in and the number of production

Gibson Skylark Lap Steel Serial Numbers List

So, for example, let’s take the serial number 80351045.

• This guitar was built in 1981 – 80351045 – remember in the format that the year is the 1^st and 5^th
• This guitar was built on the 35^th day of the year – so this would have been February 4^th – 80351045
• This guitar was built in the Kalamazoo factory and it was the 45^th instrument stamped that day.

So this serial number represents the 45th guitar built on February 4, 1981 in the Kalamazoo factory.

Factories

The Kalamazoo factory operated until 1984 and guitars made in that factory from 1977 to 1984 had the last 3 digits (the production number) that were between 001 and 499.

Guitars built in the Nashville factory from 1977 to 1989 used the production numbers 500-999.

For example, the serial number 81457556 – would be May 25^th, 1987 and the 56^th guitar built in the Nashville factory. The first guitar built that day would have the production number 500.

Guitars built in the Nashville Factory from 1990 onwards have production numbers 300-999 – so the first guitar produced that day would have the production number 300.

Lap Steel Ebay

The Montana factory uses production numbers 001-299 and this was from 1989, when that factory was opened.

Exceptions

There are guitars that will be exceptions within all of these time periods.

If your guitar doesn’t seem to fit within any of these systems, check out the resources below to see if you can decipher your serial number.

Thanks for Reading

I hope this helped you to decipher your (often complicated) Gibson serial number.

GIBSON SERIALIZATION
Identifying Gibson instruments by serial number is tricky at best and downright impossible in some cases.
The best methods of identifying them is by using a combination of the serial number, the factory order
number and any features that are particular to a specific time that changes may have occurred in instrument
design (i.e. logo design change, headstock volutes, etc). There have been 6 different serial number styles
used to date on Gibson instruments.
The first serialization started in 1902 and ran until 1947. The serial numbers started with number 100 and
go to 99999. All numbers are approximates. In most cases, only the upper end instruments were assigned
identification numbers.

White oval labels were used on instruments from 1902 to 1954, at which time the oval label was changed to
an orange color. On instruments with round soundholes, this label is visible directly below it. On f-hole
instruments, it is visible through the upper f-hole. The second type of serial numbers used started with an A
prefix and ran from 1947 to 1961. The first number is A 100.

When production of solid body guitars began, an entirely new serial number system was developed.
Though not used on the earliest instruments produced (those done in 1952), a few of these instruments have
3 digits stamped on the headstock top. Some time in 1953, instruments were ink stamped on the headstock
back with 5 or 6 digit numbers, the first indicating the year, the following numbers are production numbers.
The production numbers run in a consecutive order and, aside from a few oddities in the change over years
(1961-1962), it is fairly accurate to use them when identifying solid body instruments produced between
1953 and 1961. Examples of this system:
4 2205 = 1954 614562 = 1956
In 1961 Gibson started a new serial number system that covered all instrument lines. It consisted of
numbers that are impressed into the wood. It is also generally known to be the most frustrating and hard to
understand system that Gibson has employed. The numbers were used between the years 1961-1969. There
are several instances where batches of numbers are switched in order, duplicated, not just once, but up to
four times, and seem to be randomly assigned, throughout the decade. In general though, the numbers are
approximately as follows:

From 1970-1975 the method of serializing instruments at Gibson became even more random. All numbers
were impressed into the wood and a six digit number assigned, though no particular order was given and
some instruments had a letter prefix. The orange labels inside hollow bodied instruments was discontinued
in 1970 and were replaced by white and orange rectangle labels on the acoustics, and small black, purple
and white rectangle labels were placed on electric models.
In 1970, the words “MADE IN USA” was impressed into the back of instrument headstocks (though a few
instruments from the 1950s also had MADE IN USA impressed into their headstocks as well).

and a few A-B-C-D-E-F + 6 digit numbers
During the period from 1975-1977 Gibson used a transfer that had eight digit numbers, the first two
indicate the year, 99=1975, 00=1976 and 06=1977, the following six digits are in the 100000 to 200000
range. MADE IN USA were also included on the transfer and some models had LIMITED EDITION also
applied. A few bolt on neck instruments had a date ink stamped on the heel area.
In 1977, Gibson first introduced the serialization method that is in practice today. This updated system
utilizes an impressed eight digit numbering scheme that covers both serializing and dating functions. The
pattern is as follows:
YDDDYPPP
YY is the production year
DDD is the day of the year
PPP is the plant designation and/or instrument rank.
The numbers 001-499 show Kalamazoo production, 500-999 show Nashville production. The Kalamazoo
numbers were discontinued in 1984.
When acoustic production began at the plant built in Bozeman, Montana (in 1989), the series’ numbers
were reorganized. Bozeman instruments began using 001-299 designations and, in 1990, Nashville
instruments began using 300-999 designations. It should also be noted that the Nashville plant has not
reached the 900s since 1977, so these numbers have been reserved for prototypes. Examples:
70108276 means the instrument was produced on Jan.10, 1978, in Kalamazoo and was the 276th
instrument stamped that day.
82765501 means the instrument was produced on Oct. 3, 1985, in Nashville and was the 1st instrument
stamped that day.
However, it has come to light recently that the Kalamazoo plant did not directly switch over to the “new” 8
digit serialization method in 1977. When the Nashville Gibson plant was opened in 1974, it was decided
that the bulk of the production of products would be run in the South; the Kalamazoo plant would produce
the higher end (fancier) models in the North. Of course, many of the older guitar builders and craftsmen
were still in Kalamazoo; and if they weren’t ready to change how they built guitars, then they may not have
been ready to change how they numbered them! Certain guitar models built in the late 1970s can be used
to demonstrate the old-style 6 digit serial numbers . It is estimated that Gibson’s Kalamazoo plant
continued to use the 6 digit serial numbers through 1978 and 1979. So double check the serial numbers
on those 1970s L-5s, Super 400s, and Super 5 BJBs!
Gibson’s F O N System
In addition to the above serial number information, Gibson also used Factory Order Numbers (F O N) to
track batches of instruments being produced at the time. In the earlier years at Gibson, guitars were
normally built in batches of 40 instruments. Gibson’s Factory Order Numbers were an internal coding that
followed the group of instruments through the factory. Thus, the older Gibson guitars may have a serial
number and a F O N. The F O N may indicate the year, batch number, and the ranking (order of production
within the batch of 40).
This system is useful in helping to date and authenticate instruments. There are three separate groupings of
numbers that have been identified and are used for their accuracy. The numbers are usually stamped or
written on the instrument’s back and seen through the lower F hole or round soundhole, or maybe
impressed on the back of the headstock.

F O Ns for the years 1935-1941 usually consisted of the batch number, a letter for the year and the
instrument number. Examples are as follows:
722 A 23
465 D 58
863 E 02.
Code Letter and Year
A 1935
B 1936
C 1937
D 1938
E 1939
F 1940
G 1941
Code Letter F O Ns were discontinued after 1941, and any instruments made during or right after World
War II do not bear an F O N codes. In 1949, a four digit F O N was used, but not in conjunction with any
code letter indicating the year.
From 1952-1961, the F O N scheme followed the pattern of a letter, the batch number and an instrument
ranking number (when the guitar was built in the run of 40). The F O N is the only identification number
on Gibson’s lower grade models (like the ES-125, ES-140, J-160E, etc.) which do not feature a paper label.
Higher grade models (such as the Super 400, L-5, J-200, etc.) feature both a serial number and a F O N.
When both numbers are present on a higher grade model, remember that the F O N was assigned at the
beginning of the production run, while the serial number was recorded later (before shipping). The serial
number would properly indicate the actual date of the guitar. F O N examples run thus:
Y 2230 21
V 4867 8
R 6785 15

Z 1952
Y 1953
X 1954
W 1955
V 1956
U 1957
T 1958
S 1959
R 1960
Q 1961
After 1961 the use of FONs was discontinued at Gibson.
There are still some variances that Gibson uses on some instruments produced today, but for the most part
the above can be used for identifying instruments. For the most accurate identification you would need to
contact the Gibson Guitar Corporation itself.
The serial number will be an 8 digit number impressed into the back of the headstock with “MADE IN USA” below.
The pattern is as follows:
YDDDYRRR
YY is the production year
DDD is the day of the year
RRR is the factory ranking/plant designation number.
Prior to 1984 when the Kalamazoo, MI factory was closed, the numbers 001-499 indicated Kalamazoo production. Ranking numbers 500-999 continued to indicate Nashville production through 1989.
Since 1989, all Gibson acoustics are built in Bozeman, MT and all Gibson electrics are built in Nashville or Memphis. Ranking numbers for Bozeman start each day at 001 and the electrics may start as low as the 300s.
Examples: 70108276 means the instrument was produced on Jan. 10, 1978, in Kalamazoo and was the 276th instrument stamped that day.
82765501 means the instrument was produced on Oct. 3, 1985, in Nashville and was the 1st instrument stamped that day.
NOTE – Gibson USA goes to a 9 digit serial number in early July 2005..
The sixth number is now a batch number- batch 0 starts at the beginning of the day, and once we stamp 699, the batch number will change to 1. The first 5 numbers remain the same, the last 3 numbers will remain the same. The only difference is the addition of this batch indicator.
There are always exceptions to these rules, the two listed below are worth noting:
Les Paul Classic: This model features an ink stamped serial number with no “MADE IN USA” (just as we used on the original 1952-1960 Les Pauls). Most will be 5 to 6 digits in length, but the earliest examples feature 4 digit serial numbers. There should be a space after the 1st digit with the 4 and 5 digit serial numbers, and no space with the 6 digit numbers.
The 1st digit indicates the year of manufacture for the 4 & 5 digit serial numbers, these were used from 1989-1999. The 1st and 2nd indicate the year of manufacture for the 6 digit serial numbers which we’ve been using since 2000.
Examples –
9 xxx = 1989 (4 digit number beginning with “9” used only in 1989)
0 xxxx = 1990
9 xxxx = 1999
00xxxx = 2000
05xxxx = 2005
Those beginning with “94”:
In 1994, Gibson’s Centennial year, many instruments have a serial number that begins with “94” for the year, with the remaining 6 digits indicating the ranking number.
