Pictures Showing WWII Rotary Engine Crankshaft Arrangements: Where, Please ?

Hello;

I spent a fair amount of time searching, but just cannot find any.

I am trying to locate pictures that show the crankshaft arrangement(s), and how
they work for WWII style rotary engines. e.g., the Wasp series by P&W.

Might anyone be able to point me to a site with a few pictures ?

Very curious about how the crankshaft was arranged so as not to interfere
with the piston rods, etc.

Thanks,
Bob
