Arizona Copper No. 6

The Arizona Copper No. 6 was built by the H. K. Porter Company of Pittsburgh, Pennsylvania for the Arizona Copper Company of Morenci. 
No. 6 ran on 20" tracks. This is 16" less than narrow gauge, and 36 1/2" less than standard gauge tracks. The small locomotive measured only 17 feet long, by 5 feet 5 inches wide and weighed just 11 tons.
The locomotive was used to haul ore trains from the Metcalf mines on the Coronado Railroad until it was retired in 1922 when the Coronado Railroad ceased operations. It is unknown what became of this locomotive afterwards.
