Can anybody tell me where could i find site which deals with serial numbers of basses. I need this because i have problem identifying my own bass. It is 4-string Framus which was made in somewhere circa 73-75. And it is not Star bass. It looks somewhat like Fender Jazzmaster guitar. On the backside of head stock it has a serial# 54033 and a little bit apart a two digit number 73, which probably could be the year of manufacture, but the guy who sold it to me said that it was made in 1975.
