Thursday night History Channel here in Canada aired a very good documentary from the Jeep's inception to modern day variants.They go into black and white archival film before the war when competion began between Bantam and Willys-Ovelland for the development onto war production,including Ford variants, ending with the Kaiser,then Chrysler takeovers ,during post war years..During the first minute of the film,showing Bantam's being put through their trials,what should appear,in a cameo shot crossing a stream,two of our venerable CMP's.Boy!they show up everywhere in films.
I highly recommend watching this film.History Channel usually re-air documentaries frequently.,but you have to be ready to catch them.
