The 1930's were hard to beat when it came to perfect proportion and design. Think about all of the great motorcycles and cars that came out of this era. Knuckleheads, VL's Harley WLDR's, Indian Fours, Sport Scouts, Brough Superiors, the first Vincents, Norton International racers, Velocette KTT's and on and on..................... This is not even speaking of the aero space designs that were happening.
