I have read about several M1909s being obtained as surplus from some large bank which were used by bank guards back before WWII. I don't remember where the bank was, but Cleveland sticks in my mind as a possibility. The one in your picture is the most pristine I have seen. One of mine is fairly close but a few points less. It is now on loan as a museum display. I know nothing about the histories of either of mine, nor did their previous owners. Except that they were probably among those which stayed stateside.

Among the civilian Colt A&Ns, I'd say I have seen more chambered in .41 LC than any other caliber. I had one of those long ago, but never fired it. And it was definitely in what could be charitably called "shooter condition." Despite its well-used condition, it seemed fully functional so I assume that its mechanism was fairly sturdy.
