our Il Gugissimo reports that the Campag braze-on gear hanger tab Nr. 80/1
has been unavailabe for several decades

rather than a "5" could be the "B" from "BREV..."
and if nobody on Earth has the genuine 80/1 part in their stash, I would not hesitate to find a trashed donor frame with good forged RD hanger (Campy but if not then ANY quality brand with correct threading and profile) and cut off the segment and then the offensive hanger on this sorry frame and let a skilled brazer (or Tig welder) make it whole again!
My gut is this repair is still not for amateurs but far easier that a full DO replacement
BITD Ed Litton did that repair to my old TdF (crapified Simplex DO) and it was masterful!
