There's something strange about this. I have never personally seen a 3 bolt Jazz neck plate with a serial number that low in the 300000's on a J. In fact, that serial number is lower than one on my '72 4 bolt Js! (373965). The serial number is also inconsistent with most Fender dating sources, including The Fender Bass Book, which indicates that by '74 the serial numbers were well into the 500000s. Yet, lo and behold, right on the very same source page of that book, (104), they show a picture of a 3 bolt with the serial number, "351591". The 3 bolt neck was first introduced on the Tele bass in '72, however, so my guess is the photo in the book shows a Tele neck plate. I can only assume that there were Tele 3 bolt plates produced in '72 older in the serial number order than my 4 bolt J plate, but were perhaps kept around for marrying to the '74 (and on) Js later. So, this bass may very well be a '74 J with a '72/73 Tele plate on it, but there doesn't seem to be any other date indicators on the bass (other than the pots, which do appear to be '74).
Here's something even more confusing. I had a brand new, 1973 Fender Precision. serial # 373711, and a used, 1971 Jazz bass, # 342750 . This is indeed strange. Sure looks like a Fender plate and stamp to me, I've been repairing these basses since 1968.
I've seen quite a few Fender basses with nothing, that's right, nothing stamped or written on the heel. This bass looks completely authentic to me. I think if someone were going to make a counterfeit bass- they would be best off to shoot for a pre-CBS custom color jazz bass with a matching headstock, not a less valuable 3 bolt 70's.
