Date of P bass pick ups

[jonnythenotes]

The numbers on the back of my P bass pick ups are 180574. These are grey pick ups with the numbers stamped in ink. Does this mean 18th May 1974? I doubt this, as the Americans put there month in front of the date, which would make my theory a none sense as there is no 18th month with a fifth day in it... Also, the pots are stamped with the numbers 137 7352. I know the last four numbers mean the 52nd week of 1973, but what do the first 3 numbers mean....? Once again, any help and advice is always appreciated...

the 74 does indicate the year

I think the 137 refers to the type of pots.

As for the pickups yes the last two digits are the date i think - mine end in 70, and its a 1970 bass.

The first 3 numbers are the manufacturers code. 137 is CTS 🙂
