Very interesting and I could only imagine how rich lawyers would get today fighting over Pickard and Packard and how to differentiate them since they would be building the same thing for the same market.

Glad you found it interesting. I probably should have added that Pickard was the family name of one of the founders of the company.
The valve arrangement has similarities to that used later by the Duesenberg brothers in their "walking beam" engines. The cylinder head/combustion chamber appears to be cast en-bloc with the barrel so I assume the valve seats are within the manifolds, pretty neat piece of engineering!

The cam and rocker arrangement is interesting. Assume the large rod coming out of the cylinder head is the rocker support and pivots at the cotter key but is the white arrow pointing to a pushrod or spring. I thought it must be a spring but it would seem to be an odd location and a very tight spring keeping all the clearance at the valve.

The white arrow is pointing to a spring whose purpose seems questionable. If you look closely at the timing gear cover casting you can judge the location of the camshaft; the actuation of the rocker is in or down below the "box" that the lower end of the rocker is seen entering. Dual camshafts like a "T" head, the one for the intakes on one side of the block, that for exhausts on the other. Uncertain of the means by which the rocker follows the camshaft profile.
A really neat little engine, its advertised horsepower was 25.
