Unpainted brass narrow gauge Mason Bogie. Kadee knuckle couplers rear (Link & pin pocket is in the box). Has not been run for many years so running condition is unknown; touch-up cleaning/lubrication is recommended. One from a large collection of locomotives from my brothers estate; a 1000 sq. ft. pike featuring D&RG's Tennessee Pass and the Colorado Midland's Hagerman Pass routes in Colorado, circa 1908. This locomotive was not used on his layout.
