Yes, it could be anything.


But, if I had to guess, Id say its a serial number of sorts.


Picture it on an assembly line in 1957, hand made. One guy in the saw shop is going cut out the pieces. Maybe another guy takes the parts and does a dry-fit to ensure all the parts fit together correctly, keeping in mind the covering is going to take up some space here and there. At this point the parts would be serialized to prevent them from getting mixed up with any other parts. Some of the parts then go to the covering area; some parts go to the gluing area, and some to the paint shop. Somewhere down the line all these parts have to get back together to build a cab that fits together. The numbers are the only way to know what parts are what. I know this is very common in manufacturing of many different products. But in this case, Im just guessing

Yeah, I'm sure that it's just an example of production-floor referencing; that's definitely NOT an amp from 1965 or anything like that.


It might be of some tweaky-geeky interest to know the total for Fender Princetons produced in '57, and what months they were manufactured in, as well as any revisions made during that run.


Of much more significance is the "GF" rubber-stamped in the upper-right corner of the paper tube-chart also shown in your photo. That signifies a production date of "1957 (G) - June (F)".

Ask yourself- What Would Ren and Stimpy Do?

Production assembly numbers are a good guess, however, I just happened accross an identical '56 Princeton on ebay and asked the seller if any such markings existed on his cabinet... answer was no.


Another theory - When I got this amp it was covered in green vinyl see pic , so maybe whoever reupholstered this thing did it in '65 and marked it for posterity. The color certainly would have been popular then. Anyone out there with a mid 50's Fender amp who can take a peek in it?
