The pictures are small, but from what I can see and IronMountainPete's description of the finish on this gun, and hearing from GaryG that they were all antiqued, I'm thinking maybe this one was refinished at some point?

all numbers are mismatched on this revolver to match the Louis G. Bishop gun on display at the National Firearms museum  On the frame and butt of the revolver.  the only difference in the NFM number.  Same numbers and Proof Marks as well as RAC on the cylinder , exactly like the original.

Yessir, the Kuhnhausen book is pretty in-depth and a great resource. I was taught by Mr. Jim Martin that explains the steps and the do's and don'ts in that particular book.  Do the hand first. Once you have the bolt (currently in it) dropping in the locking notch simultaneously with reaching full cock, the hand will be the right length. Then you can deal with "bolt drop".

GaryG, Were all the guns sold through Cherry's only and was the one on display at the shot show the only all US parts revolver made?

I don’t know how many of the Rough Rider guns were built but as the serial number suggests there were at least 40 (Uberti) sold through Cherrys.  At the 2005 (maybe 2006) Shot Show we had a Rough Rider gun on display.  All US parts, mis-matched serial numbers and “antiqued” the way it was orginally done.  The parts were rusted and then rusting process stopped.  The guns had a light freckling and looked old.  The problem was if the rusting process wasn’t totally stopped, rusting would continue after the gun was boxed and shipped.  A few got out and were totally rusted/pitted upon arrival at the dealer.  The process was eventually changed to a wire wheel, steel wool and oil.
