BTW, in 76, Gibson start numbering the serial numbers different. 76's have a serial number on a decal, and start with 00. I have two 76's. An es-175, and a B45. This is from the Gibson site:
- From 1975-1977 the number is typically found on a decal on the back of the headstock. This should be an 8 digit number that can be dated by the 1st and 2nd digits as follows:
99 = 1975
00= 1976
06 = 1977
- In 1977, Gibson introduced the serialization method that we primarily use to this day at Gibson USA, Gibson Acoustic, and the Gibson Custom facility in Memphis, TN.
