The Morrison branch was closed in 1926, from what I read. It looks a lot like CONX #17 but that was on the D&RGW. Apparently Conoco built nearly all of the cars with C&S parts, presumably in Denver. I would like to know if any of the cars that were on the C&S transferred to the D&RGW after the 1930s abandonements. After 1945 Conoco sold their reamining narrow gauge cars to the NdeM, where Adolf Spotted Dog photographed them in the 1960s. Some of the steel cars migrated to Guatemala.
