I'm not familiar with the headstock logo. I'm pretty sure the large letter is a B but I can't make out the top portion. The B looks like some I've seen on a few Harley Benton guitars - maybe the top portion is an H.. can't tell.
I found a HB headstock with the same script B on it - part of the full name, not initials. Going by this alone, I'll take it as a Harley Benton but no idea which model. Their current models don't have this particular logo (see first post). Could be an older model I suppose, lots of older model everythings around.
