I still have the pup, bridge, tuners and one knob from a 50s EB(1) and half a 58 EB2 headstock, and several black pup covers. I figure one of these days I might buy a 50s project. Or make another Explorer bass. I also have a Cinemax Les Paul day-glo blue bowling shirt that I won. It was a contest to win a LP custom from the early 80s. I didn't win it, but I got the shirt. There are lots of old guitar trinkets and do-hickeys that I have kept. All my vintage basses got stolen, but I kept the parts and paper stuff. That is life.
I sold off my old drum stuff on ebay, and that was a rewarding experience. I never played the drums.
