Meet the Cooley's, father and son, the men responsible for these extremely rare engines, so rare in fact that there are none of these Cool engines left in existence!

Here is a Cooley launch engine, complete with gear. Notice the Central Vermont Railway cars in the background.

Here is the Cooley shop where these engines were built. Notice the Bolt threading machine on the left. Also check out the odd little marine style engine. I remember seeing one of these in a book once. I think they called it a Naptha Launch Engine

If you look closely in this picture, you can see an A.W. Gray  block, and the crankshaft is on the bench. Also note the odd little upright engine.

Now this is something I wouldn't mind finding in an old barn somewhere! None of these Engines are Known to exist. That doesn't mean there isn't one out there somewhere!
