The big bore revolvers ought to be whatever Pietta is producing as an 1873 clone. I wouldn't expect any non-steel or brass parts that aren't in their regular line, but I suppose that depends on just how finished the gun is before Heritage gets it.
Which rimfires do they make in steel? Are any of the Rough Riders? If so how do you determine which is which?
