I'm trying to refinish an old reed organ. The outside is basically a tall skinny desk with a shelf on top. The wood which should be tiger-striped appears to have been very poorly stained years ago. It's almost like it was painted black. There doesn't appear to be any "varnish" or other sealer as the wood has no sheen and has a slightly rough, dry unfinished feeling. This may be due to having been stored in an unair-conditioned building. I've begun sanding it, and can clearly see when I've gotten through the outer layer, but the wood underneath is spotchy in appearance. I don't know if I should continue sanding or give it up and try a chemical for a better, more even outcome. Also, there is a lot of very shallowly carved designs on parts of the organ and I won't be able to sand the finish off of these. I tried to include pictures but am not sure if it worked. Any advice on what to do would be apreciated. Do you think that the part with the carving is irreparably ruined?
