I just inherited 3 Gibson Mastertone banjos from a very close friend of mine, He wrote me in the will and said to sell them to help me buy the Harley Davidson that I always wanted , of course this made his girlfriend mad but I cant care that was our joke to the world. Anyways one of them is easy to tell what it is because on the neck it clearly states RB 8oo and I can look it up by the serial No. 06189047 but on the other two I can not find a serial no. anywhere on the instruments, they clearly say Gibson on the top of the neck in pearl and Mastertone further down the neck but no serial no. How do I find out what series of banjo I am trying to sell without any noticeable model number? I was hoping someone could help me so that at least I could be somewhat informed about them before I attempt to try and sell them.
