I have a sales brochure at home somewhere from 1930. The standard six was basically the 612 from 1930 (So the 115 inch wheelbase, but 3 speed transmission). From memory The factory had the 2 and 4 door sedan, 4 door tourer (also known as a Pheaton), 2 Passenger Coupe and roadster, I am pretty sure the coupe and roadster were available in either business (boot hinge at top) or with a dickey/rumble seat. Though outside body builders, exports often used outside body builders, would build you whatever you liked. Note "De-luxe" was a trim upgrade. I see the above mentions a Town sedan, not sure what that was, may have been a delete of the rear quarter windows, will have to look at my brochure
I have somewhere a pic of a Australian bodied 4 door tourer, the only other standard six's I have seen were a 4 door sedans and I dont have pictures.
Why do you ask?
