Does anyone have any information on the Railway Motor Car Company of America, a builder of speeders based in Hammond, Indiana in the late teens? I've come across some materials from late 1920 that indicate the company was trying to relocate, but I don't know whatever happened to RMCCA. Included is an interesting sales booklet with illustrations of various doodlebugs and gas- or distillate-powered locomotives which were probably never built. A quick online search also revealed the following web page:

Any help is appreciated - thanks!
