Data from Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 166. See Locobase 13800 for a description of the Ray Consolidated Copper railway. Works number was 4875 in June 1911.
The R&GV listed the engine as "stored" in February 1946. Unlike the other locomotives on the roster, however, this one was shown as "out of service since 1/1930."
