Default Vintage Airplane Engine Crankshafts trying to ID

Hi -

Was hoping some of the Airplane Engine enthusiasts could help ID these Crankshafts. They are both
from the same manufacturer, but different.

Having a tough time, anybody ?

Thanks!

Looks a whole lot like early Quadra Q 35 - 40 cranks. One has the offset grind for ignition points. They all used that one counterweight design with individual loose roller bearings lined up on the crankpin. The one piece rod slipped over the crank and into place. Seemed crude at the time but it worked.
