My OOTF reports that this vehicle, first shown from the front the other day, is now identified!
It’s a Dodge M37. Began production in 1950 for the Korean War and continued until 1968. Nearly 111,000 were built and some are still running today. Top speed is 55 mph and they get about 9 mpg.
Nice to have vehicular mysteries solved. Thanks for the research, OOTF.
