IDing year of manufacture and other historic info on most of these old imports is liketrying to id old tupperware. Not gonna happen. You just have to enjoy the funky vibe for its own sake. My first electric was a Kent played through a very tired Barcus Berry amp. I don't remember much about it aside from it was cheap to buy, made the neccessary electric guitar sounds....when it worked. Wish Id applied myself more to learning the guitar way back then. Wish I had that old Kent back? Not so much.
