1918 McCormick-Deering Model M engine. This one is an earlier model with the understrike igniter.

I’ll be adding a few posts and photos as I describe the work done in cleaning up and starting up a 1918 McCormick-Deering (International) 1-1/2 horsepower Model M engine once I figure things out here.  I have already done a good bit of the work, so this is all a catch-up game now.
