Very nice! I don’t believe I’ve seen that particular model with the folding hammer before.
Yeah, it’s pretty cool. won’t snag on your pocket. It’s probably antique. The factory burned down, so no records left.
My late Brother bought a Colt New Service in .45 Colt around 1965. He bought it from a retired cop. I am not certain but I think it was pre WWI. Fixed sights and a grip adapter to make it easier to hold.
Again, a really really smooth action.
