It's very close to an RBX-170 except it has only a P-pickup. Volume, Tone, and output jack, black lightweight body and a bolt-on neck with rosewood fingerboard. The serial number begins with an 'M' and it doesn't indicate where it might have been made (but it wasn't the US or Japan ...) and I suspect it sold for under $200 new; I paid $80 in fair condition. Surprising, it sounds pretty good. Any guesses ?
