I have seen the red, blue and even a few yellow cascade engines. that one you have posted is awesome. McCoy jr also had a white 4-6-0 posted a few years ago. It looked so neat but the price was crazy!
I dont know why the McCoy stuff is so interesting to me. Maybe its because it was such a family based operation. Heck, I cant even figure out why I favor tinplate over postwar or even scale trains. Must be the metal, or the nostalgia. But I for sure enjoy tinplate the most !!
