Silvertone Tenor

Sorry, didn't know which vintage sax forum to post this in. Anyways, today I visited a a pawn shop with a hoard of instruments, and they had a silvertone tenor for $600. It had split bell keys and the spatula looked kinda like a buescher 140's. It had little button resos. I compared it to a winston they had, and it was slightly shorter and wider, but not enough to be a C melody. I've read this is a buescher crat stencil, but it looked more like a conn chu. Can anyone tell me what this is? Would their price be good (considering it needs an overhaul)?
