I recently saved/salvaged this from a derelict building. It obviously had come into contact with a bit of moisture. It is a plywood bass with no markings other than a label on the inside of the back with "No. 211" as best as I can make out through a magnifying glass. I wouldn't have bothered if the back, neck, and top had not been in such good shape. At this point I'm trying to decide whether to reglue the delaminated sides or replace them. The mold is a definite consideration. Does anyone recognize the V joint at the heel/back connection?
