1950 Grover Archt. Short Tailpiece

I’ve seen these before and they’re rare. Possibly as old as the 1930s, no way to prove it either way, and extremely solid with beautifully cast cross-bar; have seen this exact one on myriads of types of earlier Grover tailpieces, including those made for Martin. Bail ends threaded, one nut missing, looks like an 8-32 or 6-32 thread to me and should be easy to replace. Beautiful old-time heavy nickel plating. $95
