Please help me figure out what I have...This is a gun that I bought as part of a collection from a Widow. The collection had only high-end guns (this is the least valuable) so I think it must mean it is more special than the average NAA due to the collector (He had matching Volkmann 1911's and several Pythons and even a Perazzi) I only bought part of the collection and couldn't resist this NAA...it's prettier in person and is mint. Doesn't look like it was shot, just collected.

Anyway, I know it's a Magnum but is it a special run of Factory engraving or did he possibly have it done? What about the grips? He didn't have "stock" grips so maybe it came this way?

Any insight would be great so that I don't sell it too cheap when the time comes. I've got it loaded up but haven't shot it yet in case it's something that I shouldn't shoot due to value.

Thanks in advance!
