Beautiful 38 Royal! I can’t help you with Canadian production breakdown, but 2,850 Royals were built in Windsor, Canada. My father bought our 1938 Desoto Rumble Seat Coupe in 1969 or 70 and it is Canadian built as well (it had a total production US & Canada of 38 - 27 US built & Canadian production of 11 and ours is body #11. 1938 was last year for the rumble seat so it is the last Desoto Rumble Seat Coupe ever produced in Canada). I’m curious to see the production plate on your car as I believe they could be the same colour (if yours is original). The paint code on mine is 642 or possibly 648 as the last # is not stamped clearly. Any info we can share would be greatly appreciated. Finding information on Canadian built pre-war Chrysler products can be extremely difficult, so if we can assist one another would be nice.
