I have only seen pictures of DeSoto trucks. They were captioned as being taken in Spain. I have seen several Stewart trucks. I go to a couple of truck shows in N.Y. every year. One near Buffalo and one at the other end of the state at Ballston Spa.Nice. I love seeing the old trucks when I go to shows. Have you ever seen a DeSoto truck or a Stewart at any of them? The DeSoto would most likely be a rebadged Dodge or Fargo and the Stewart was made a couple hours away from there in Buffalo, NY. Nobody in my neck of the woods has ever heard of them other than the Desoto car and sadly most of those people are getting up there in age so there's not many of them left to get info from
