I've seen these before in antique shops. Sometimes you can find them in the original box unassembled. There weren't alot of craftsmanship kits like this out pre ww2. If you wanted a particular item you would have to scratch build it. After ww2 a lot of returning GI's started up small company's making model train stuff. Theres a good book by Carstens publishing that talks all about these. It's called 150 years of train models. C95.
