I picked up what I believe is a Hamer Blitz bass. Here's the issue the headstock looks like it might have been painted and HAMER letters stuck on. No Serial number on the back of the head stock. The Tuners say Hamer with what looks like a lockset screw on top of the tuner. Hamer USA bridge and looks like old pickups. Any help in tying to nail down what I actually have here is appreciated. Had a hard time finding out any details online. details Hopefully the pics will help.
