I picked this one up today from a friend. Your comments please as I know very little about these. I do know that most had the brass trigger guard.
It's anodized aluminum. That's why if you nick it, the dent will show white metal below and it can't merely be polished out like brass could.Cute little bugger! I don't think it's brass though. Aluminum that's been plated/treated, I may be wrong though. Very collectible whatever it is.
