Is this the car built in Salt Lake City on a 1929 De Soto base with Ford flathead power? In which case I think we've had it before.
It was built around 1953 by John W Campbell of Issaquah, Washington. It definitely has the 1929 De Soto chassis, but some sources say it's a Mercury, and some a Ford. Not much difference really. It's called the Double J Special. It presently resides in Norway.
It doesn't come up in a search, but I think this was one of carnut's puzzles a couple of years ago.
