Chris,
This is a fantastic find! I think I've only seen the one with the cab remains nearby.
I believe there were three Souther engines brought in originally, two during August 1872 (#1 - Gen Sheridan, #2 - Gen Sherman) and a third, likely numbered #3 but apparently un-named or I just haven't run across a name so far. I've not seen a receipt date for the third Souther but suspect either August or September 1872.
The first Porters arrived in March and April 1873 taking open numbers #4 and #5.
During February/March 1875 the CCRR did a realignment of engine numbering into something presumably more logical. On 27 Feb 1875 #2 Gen Sherman and #3 were fitted as switchers and lost their numbers, becoming only discussed as "Punch" and "Judy". On 6 March 1875, #1 Gen Sheridan was shipped to Omaha and never returned to Colorado. At this time the D&B/National/Porter engine #6 (first), built April 1874, was renumbered #1 (second). In June 1875 two new Porters (c/n 214 and 217) arrived numbered #2 (second) and #3 (second).
Concurrently, on 17 Feb 1875 the CCRR Golden shops were reporting building tender frames for a Souther and the expected two new Porters (second #2 and second #3), presumably 4-wheel tenders.
"Punch" and "Judy" worked primarily as switchers until being sent to Omaha 4 June 1879. They never returned to Colorado.
