The Dusenberg 4-valve OHC cylinder head combustion chamber looks very much like a DFX Cosworth.

Year late and a dollar short, but I never knew the Dusenberg used quarter-speed cams. Now we know where Bus Schaller got his inspiration.

I think that Jack is correct insofar as sighting along the shaft would superimpose the cam lobes and provide an inspiration to a receptive mind. Bus would have known how to achieve it.
