Here's what I got off the Critterslist so far, isn't much either. I've got a little HO scale model of one that I have been building for some time, its half-done but I haven't worked on it in a while. This message is from Mike Bauers:
"Only 11 20 and 23 ton of that style were built in 1938 and 1939. There is a picture of a standard gauge model lettered 'Lehigh Cements', in Mason City, Ia, 9-25-74."
The info came from a new book I want to get called "Critters, Dinkys, and Centercabs", but that's all he could find in that book about it. It would be nice to have in Chama, but they just got a good working Brookville. A friend of mine knows a guy who works in the Chama shops, and works in Arkansas the other half of the year building custom Hummers. We could get one of those too, and they're more powerful than any little locomotive!
