For what some of you have spent on a couple Accucraft G scale locos, I got THIS…
My ex-wife sometimes called it a 17,000 pound (well ok, it does weigh 17,340# dry) doorstop…
It is a 1917 25 horsepower 20th Century Mfg Co traction engine, made in Boynton, Pa. It has twin 7-1/2 x 10 inch simple cylinders, a 42" flywheel, and is still running at 125psi. The original wheels and undercarriage were lost to the WWII scrap drive, and the engine and boiler were placed on a '56 Ford chassis back around 1960. It is one of only 3 (and another half) known left from this builder. Pic from about 1935
