I have a few McCoy Diesels, although I haven't done anything with them yet.
Adrian Duncan of Model Engine News has a good story about the engines too.

McCoy .09
McCoy .049 Dura Glow diesel Replica engine. It is a P.A.L. replica of the McCoy .049 Dura Glow model diesel engine from Bob Langelius. I am not sure if he has any more though <cite>

McCoy .049 Dura Glow engine, not a replica
Comparing the replica to the original
I also have a crankshaft and crankcase for a .049 McCoy engine too. But the crank does have some corrosion damage on it though.
