Hi, I have been racing pre-war 3 wheelers in UK since 1970, so there is a good chance I may know of the car before it went to USA. Also, I could put you in touch with someone in USA who is a MTWC member and very knowledgeable about 3Ws in USA. PM me.

The MTWC is a terrific club with much technical information in its monthly magazines since 1945. The mags are available as a CD and there is an index of technical articles on the club website for members. It also has an excellent spares scheme called Mogspares which is run by dedicated volunteers. Not everything is available all the time, but it's a good starting place.
