Alternatively, I have another 84-3 waiting to be sent in with work request already submitted. Red and green points. Butt is perfectly straight with very tiny nicks and dents that are hard to see and likely resolved completely with refinish. One tiny ding on edge near bumper. Matching shaft is period correct, pre-dot shaft. Shaft has the tiniest bit of wobble (about 1mm gap in center when rolled on the table), but shaft is just straight taper. Pro-taper would easily make it arrow-straight. I don't think shaft is original to the butt. If you line up the joint collar on butt and shaft, the ring design on the shaft is about 1mm wider than on the butt. Hard to see unless you look very, very closely, but want to be transparent.
Wrap is solid white, uncoated wrap with wear and stains, so needs rewrap anyway. Tip diameter at base of ferrule is 12.8mm.
Was really planning to keep this one but probably a good candidate for you, depending on what you want to spend.
