Thanks for the welcome and information. Now, does anyone have the time to explain the planetary arrangement in the differential? It almost looks vaguely like a torsion type limited slip, but I'm not sure they were working on that type of deal in the 30's. 2 speed rear end maybe for a cruising gear? Were the planetaries there for further gear reduction in the differential case? Possibly I'm just over thinking things and they are just another approach to spyder gears for diferentiation in wheel speed while cornering. Dad got the classic car bug, I ended up with the "take it apart and figure out how to make it stronger" bug. Between the two of us, we pretty much have the field covered. Helps that he had me lappin valves on a Morris 8 before I could ride a bike.
