Some common makers but not all codes are these... Also, I know everyone has a different opinion on PU's, but as the PU's in this guitar have no covers and are crappy looking I will be ordering a set of gold covered???? Many also put a country of production.
Since your guitar has pots dating from 1971 and they appear to be original, we know it was produced in 1971 or la.

This Gibson pot database contains part numbers with respective models for all Gibsons from the early 1960s until the early 1980s as described in the various replacement parts lists distributed by Gibson. As always with Gibson, there a probably many vintage guitars that don't conform to the catalogue descriptions, which are often incomplete and may even contain errors. Gibson pots are NOT all the same. Most 60s-70s Gibson potentiometers were made by CTS Chicago Telephone Company , although other manufacturers did also supply pots to Gibsom. Pots usually have several identification numbers. One is the manufacturers id code with date, and another is the Gibson part number. I have seen many seemingly-original pots with codes that do not follow the typical Gibson numbering, and many that just do not conform to the correct resistance values as described in the schematics. Gibson, no doubt, used parts that were available, and no doubt CTS and other pot supply companies shipped replacement parts from time to time. As with all Gibson rules, these should not be treated as absolute. If you want to discuss or add data provided here, please start a thread in the section of the forum.
