Here is a western entry that I love to shoot. This rifle is about .48 caliber and has a 41.5" barrel that is 1 1/8" across the flats. Can't prove the Colorado connection, but the architecture screams it and the old fellow I got it from says that is where it came from.

I really don't know anything about this rifle except it looks like a western mountain rifle. It does have a couple of features that are rather unique to me and that might help match this rifle to others by the same hand. The side opening cap box with the button in the comb of the rifle and the square step feature of the tang might just let us identify this rifle by comparison to other rifles with these features.
