Looks very similar to the OM318. There is one sitting in a barn near me, with a 5 spd tranny with it. It was taken out of a bus, and used in a small saw mill. It didn't have enough power for the mill so they took it out and is sitting in a barn a few miles away. I could have had it for $350. I'm not sure if it is still there. I would have bought it to put it in a 1/2 ton truck, but it is so tall (36"), clearance is a problem. So is oil pan configuration.
