Hi Andy:
Thanks for your response. As I said earlier; the only person I ever showed these photos to was Don Boyle and he stated without going into any detail that it was a legit. ring. He was also non committal regarding the documentation. Again; and in retrospect, I regret that I didn't pursue this ring more actively but it was pre Internet days for me and I was living in the Mid West at the time and the antique shop was in New England. I guess it will remain one of those unsolvable mysteries. I don't doubt that Himmler's daughter has at least one of his rings. However; I suspect given his status he had multiple copies.
Jim
