Your poll does NOT have all the body styles! In '31 one of the three slant window fordors, the 160B was a "Town Sedan". The 160's were made by Briggs, Murray, and Ford to identical prints, all body parts interchangable. They were not specifically I.D.'d with a body builders tag, but minor fastener details may reveal who made the particular Slant Window 160x. My Town Sedan (160B) was made by Murray, I think. The 160A was a standard slant fordor and the 160C was a Deluxe blindback slant fordor. I believe, technically, only the 160B was called a "Town Sedan". The 160C was a "Deluxe fordor". I'm not sure why the 160C wasn't a "Blindback Town Sedan".
