Hi,
There was a sister to the two CRRR 2-8-0s. It was numbered and built as CRRR #11 as an 0-8-0 and then converted by the builder to a 2-8-0. The C21's were duplicates to the #11.
Apparently, what was intended as CRRR #11 became Columbus & Rome #4. It was absorbed into Central of Georgia as number 804. It then went to the Gainesville Midland Railroad (number unknown) and finally ended up in Cuba at Cia Azucarera Mendozo. The loco was purchased by a US citizan from Castro's Cuba for repatriation. It is doubtful that the locomotive survived Cuba's scrap drives - there is no known confirmation yeah or nay.
