I found this instrument in the local want ads, with a "best offer" price tag. Needless to say, I fell in love. But before I start making serious inquiries, I'd like to know a little more about the instrument than "I don't know. It's old. I inherited it from my grampa." I've spent about a week looking. All I've been able to determine is that it's not an Epiphone, Eko, or Warwick. It might be from the 60s. It may be a one-of custom hand-built job. It may or may not be DDR/Soviet Bloc. Does anyone here recognise it? What would you offer?
