Thanks Rolly,
It looks like the Delling is close, but maybe not quite it. The engine here is a compound, and I don't think the 2 cylinder Delling is.
I did find a little about the Dillon though it dosn't seem to be a match either. Curtis H. Dillon did form a company (1919-1920) to make steam engines for tractors, trucks and automobiles using his patented engine design. [

Don't know if they actually made any.
