I doubt you see many of these much on the lines at Camp Perry and it probably wasn't made by Smith & Wesson
. Other than that little bit of insight, I haven't a clue-though, I do agree with aarondhgraham in that I suspect it was made in Belgium or France or some such place. Gary, Indiana comes to mind.
In any event, welcome to TFL, Mule27. You'll get the right answer soon enough, I'll bet.
