Is there such a thing as a "1931 Model A Pick Up" that was built in 1932. If so would it be considered a 31 or 32. I ask because there is a guy selling a Model A truck who insists it is a 32. I know however that the Model B was introduced in 32 and I am trying to get an accurate idea of what this truck is. I am sure it is a model A. Could it be that the last of the production year 31 models were actually manufactured in 32??
