This means that the Pot was manufactured by CTS company in the 15th week of 1974.

In the second string of numbers, the first three numbers are a code identifying the manufacturer.

The next two numbers after the manufacturer number are the year, and the last two numbers are the week of the year the pots were made.

This should never be the only method used, but quite often it can help back up evidence already acquired to date an instrument. First you need to get underneath, to the circular disc on the bottom of the shaft at the opposite end of the knob (which may, or may not, have to be removed depending on the instrument).

In most cases if it’s not made unreadable by blobs of solder, you should see a six or seven digit number.I’ll start with trying to date the instrument, but keep in mind that dating and identifying Gibson guitars typically go hand in hand.I get several questions about Gibson serial numbers every day, and my initial answer is always to not expect or rely on the serial number alone to determine the year of manufacture.This means that if you don’t have a basic ballpark of the period an instrument was made prior to the 1960’s then Pot codes won’t really help you.For example, the Pot codes you can make out are: 1377415.The codes were created by the Electronic Industries Association (EIA) in 1920s to identify the product source and date of manufacture.
