Run With The Fox,
Thanks for the compliments, largely unearned though. To ID the 1891 it would help to check the Crest on the receiver ring to see the country of issue. I think, without checking, that the 7.65X53, and 7.65x54 are the same cartridge. Some countries don't include the rim in the nominal case length, and most do. Also "rounding off" results often enough in nominal case lengths differing from the actual. In any case, the 7.65 is a fine cartridge and at one time was popular enough that it was chambered in some American commercial rifles. I agree prices have gone "out of sight".
With regard to the Wounded Warrior Project, I heard the same things you said. I don't know if what they were making is out of line compared to other well-known charities. I thought we should support them, but both my local American Legion Post and the District disagreed, for the reason you gave. A 100% of nothing is nothing and that doesn't help wounded warriors very much. I think Tunnel to Towers does good work too.
