'41 Merc. Seattle would hint it's Canadian, but I don't know if that was a Canadian 'Merc' or a U.S. conversion...if so, right around WWll, for the gas ration stamps
OK. Must be the car converted to pickup? It doesn't look like the 41 Merc pickups I found. It does look like the cars. Hudson was the closest truck I could find to it. Looks a lot like the 46.
