There must be something that I don't understand here. Ford made model A's for 4 years. The 1928 and 1929 models had a "stepped" cowl, in which the front door jamb stuck out about 1 1/2" past the cowl on each side of the car, and the 1930 and 1931 series had a smooth cowl, that is to say, the sides of the cowl ran in a smooth line from the hood side panel back to the door opening. The roadster you show in the post has the smooth cowl sides. Did some body manufacturers have a different style of cowl within the same model year?
