I have a German bow that came with my bass that I bought back in the early 70's. I never got the hang of it and I would really like to trade or sell it towards a decent French bow. I'm using cheap ones now and I would really like to upgrade. Can anyone suggest where in the Phila area I can get an honest appraisal of what it is worth? I have some pictures of it that I can email if anyone wants to see it. Can't quite get the hang of posting pictures on this site yet, I keep getting the 500 k limit message.
