I was told to check the potentiometer date codes, which all have “1377142” impressed into them.

Since your guitar has pots dating from 1971 and they appear to be original, we know it was produced in 1971 or later. Your guitar has cosmetic features and specifications similar to a Les Paul Standard.

However, the Les Paul Standard model was not produced between 19 (it was officially reintroduced in 1976).

It usually takes more than just a serial number to accurately identify and date them, and there are numerous other dating systems and tools that I haven’t mentioned here.

Some serialization systems only apply to certain guitars, and in some cases the same serial number has been used on multiple guitars!

Based on the charts originally compiled from Gibson’s shipping ledgers by author A. Duchossoir, the serial number you provided could have been used on Gibson guitars produced in 1970, 1971, 1972, 1974, or 1975.

The most important dating feature on guitars with six-digit serial numbers is that, starting in 1970, Gibson began stamping “Made In USA” near the serial number on the back of the headstock.
