Purchased an early 80's Tomos Bullet. Can't find a VIN anywhere on it. No apparent damage where it the frame stamp should be. Located where foil stamp sticker should be but, it has been removed. Also can't find anything stamped into fork except "Tomos" and what appears to be the letter "Z". Former owner was in Maryland and has several unregistered peds. I'm in PA and in desperate need of the VIN to register and get riding. Any suggestions?
