The nut width is about 1. Does the pots date the same?? But, with more than 75 years of shipping records in the Gibson books, and dozens of variations on numerical schemes used over the years, serial numbers sometimes do little to shed light on the origin of a mysterious Gibson. The first number is The years will be contained within those numbers. I also have a Kalamazoo made Epiphone Sheratan. Like a fingerprint or a social security number, the series of digits inked or impressed on the back of a Gibson headstock can go a long way toward identifying a guitar.
It can take Davidson several hours to locate a specific serial number, if he can find it at all.
