Here is an unidentified engine that I now have running nicely.

There’s no name on it but from my research, I believe it to be a circa-1910 dirigible engine. It weighs about 130 pounds, is a 4-cycle V6, has an aluminum crankcase split vertically and a 2-3/4-inch by 3-inch bore and stroke. The bronze connecting rods are safety wired and there is no internal oil pump. The brass intake manifold was caved in, and the motor mounts were broken on one side in an accident. The brass sparkplugs all read “SOOTLESS 1905.”

I took it to the Glenn Curtiss Museum in Hammondsport, N.Y., and they agreed it was an aircraft engine but had no info on it. Any information would be appreciated. Stiles Bradley, 6919 Hutchinson St., Pavilion, NY 14525; (585) 584-3815; pbradley@bluefrog.com.
