Hi, I came across a bass for sale locally here in the UK - it's listed as a German instrument circa 1870. Doing a little research it seems to be a 5/8 sized "blockless wonder". From the pictures it looks pretty beat up, but worst of all apparently some genius butchered it with some kind of polyurethane stain. The ad says that it had "internal repairs" done 5 years ago, I don't know if that included fitting a neck block (I suspect not) or bass bar (these things tended to have integrated bass bars). It also had a neck graft. It listed at £1,700. Assuming it's structurally sound is it actually worth anything? Is it possible to remove the poly finish? I think I can see the original finish underneath in some areas where it got dinged. I'm gonna go try it out to see how it sounds. If its good I'd be half tempted to make a low ball offer, with the idea of fixing it up as a project.
