Gee, a lot of railroad subject posts here. For those who like fancy paintjobs on steam locos, I built this Denver, South Park and Pacific Mason Bogie in On3 in the early '70s.
The lead truck wheels, drivers, and side rods are from the Kemtron Mogul kit. The rear truck is a Bechtold brass passenger truck, highly modified. The domes are Backshop, and the pilot (cowcatcher) is Kemtron from the early Rio Grande C-16 kit. Everything else is scratch built. And I painted it.
In 1959, United Models imported a model of this engine, but since only 100 were brought in, it was impossible to find someone willing to sell one. When I switched from HO to O-scale in 1969, it was one of the engines I dearly wanted, but I just got tired of waiting for one to become available. It was the ninth loco I had built, the fourth one in O-scale. Entered in a model contest, it was disqualified because the judges wouldn't believe it it was not the United version.
