Robert Earl Gray founded "Pioneers Of Power" toys in the 1970's. These are photos of one of the all-aluminum toys he made back then. He was inducted into the National Farm Toy Museum's Hall Of Fame in 2005. His models were made with "Koy-Loy," a high-strength aluminum alloy used in industrial bearings. Obviously, Mr. Gray had expertise in casting small parts. He used to advertise his toys in the various magazines devoted to steam power, such as "Iron Men Album." A copy of one of his ads for the Buffalo Pitts Engine is posted elsewhere on this site. The engine listed at $12, the Water Wagon (assumed to be Buffalo Pitts, as they did manufacture such optional equipment for their engines) was $7.20, and the Red River Special Thresher was $11.50.
