I bought a Washburn hollow-body electric back in the 90's from a pawn shop. There's no serial number or model number that's obvious. Looking inside, there are a couple of east asian characters penciled onto the back (I'm guessing Japanese) along with what *looks* like "HB 75" (which doesn't correlate to any guitar I can find online). The metal tailpiece seems pretty rare/unique, and the only example I can find is this video of what is identified as a J-10 (but with different coloration):
Here is a photo of my guitar:
Can anyone shed some light on this instrument???
Thanks!
