I'm with Bent Ramrod (Post 9). The Cimmarons are probably the gun for the true Peacemaker Nerds.
When I used to work in gun shops, I bird-dogged a Cimmaron for Dad so he could check off the Peacemaker box in his collection. This was the 5.5" "Artillery Model", that back in the Spansh-American / Philippine Insurrection day were arsenal re-works of beat up Indian Wars 7.5" Cavalry guns. Cimmaron paid attention to having the correct early ejector and cylinder retention format, and went to the trouble to copy the markings. They've got a couple other "Period Correct" offerings like that and the finish is NICE. I ran about 150 full-pop Triple-7/RCBS 270-SAA loads through it in one sitting a couple weeks ago. Even though it's not "True Black", it makes for a satisfactory ninja smoke bomb to hide behind as you run away. The action got a little stiff toward the end as the carbon built up. Hopefully, the Cheyenne will have re-thought their plans before things get that far.
