Picked this up cheap recently, and opened it up to check on the rubber gaskets holding the keys to the levers, but turns out there's no such thing on this model and the butons are riveted to the levers.   It plays pretty well as-is, decently in tune, just needs new straps, so I put it up on the Sales section as-is to be inexpensive for a novice who wants to do sea shanties or whatnot.
