Ok I will take a stab at it here. If my information is correct, and you are looking for a door that is period correct, then you will want a door from a 47,48,49,or 50. The info I have is 50 was the last year for one piece door windows, with a twist door handle. 51 was the transitional year with one piece window, but push button door handle. From then on it was a vent window, with a push button handle. If my dates are off someone with more knowledge will correct me.
