Which was the car with the mid-mounted rotating crankcase radial? What an item that would be.

The only rotary engine with which I am familiar is the Wankel where the case was stationary and the crank was turned by a multifaceted and convex-faced head (not a piston) fired upon by a single sparking plug.

It appeared as a HMT.net post, danged if I can find it. Position looked right over the differential.
I notice an interchange between radial and rotary. Car described is radial power. My mistake.
