Hi guys, I just signed up to this forum and thought I could help this discussion a little. There's a wealth of automotive texts available online dating back to the early days of motoring. This book, scanned as part of Google's book search program, discusses the design of automobile and truck bodies as of the early 1920s. There is a section on the design of door hinges (there's more to them than you might think), and some comment on their placement: "...The most used method used is to hang all four doors at the front. The next method, and really the best one, is to hinge the front doors at the front and the rear doors at the rear. Hinging the rear door at the rear gives a much better opening to get through and offers some protection from the rear fenders." (P.63). http://babel.hathitrust.org/cgi/pt?id=mdp.39015002942632;view=1up;seq=67 The principles of automobile body design, covering the fundamentals of open and closed passenger body design, (1922). As a side note, this volume also discusses various body types. Some such as the coupe are familiar, while others have passed into obscurity.
