Yeah nice! I remember some of Dons early CoAs would have a 'die struck ring' or similar. And now ,,he doesn't mention it at all. Many years ago the HR was a neich [spelling?] collectable .. So rare a thing many hadn't seen one and knew nothing about them. Don Did do the early leg work and I'll never take that away from him..
But now,,,well, he's going by looks ,,,like everyone else... He can't write a ;Nice die struck ring by Otto Gahr' etc etc.anymore,,,,

,,well anyway..

Congrats on finding all the paper.. It certainly is interesting,, and definitely adds to the value to the ring even if the guy is a paper pusher.... Great catch on the ring and nice work on the research.....,G.
