I'm trying to remember of Hotchner's book mentioned the gun. As to cut up parts of the gun used, I don't mean to question the ethics of the person who produced them put I suspect a cut up section of the gun would fetch a handy price and since there's really no provenance?

Truth is, It makes little difference. I wouldn't be interested in owning a useless peice of the suicide gun but I'd be honored to own one of Ernest's guns.

As to Hemingway being screwed up, I don't think he was exactly a role model but I suspect most of us would not look too good if a half dozen people chose to investigate every particle of our lives and report on that which was most "interesting."
