This enigine is complete and is a twin piston fully working model. It has a standard pressure relief valve, and a brass type whistle, with an end boiler water level glass sight. The burner is a solid fuel tablet type. There is one boiler outlet pipe to the piston heads, and two returns to the detachable chimney. It is fitted with a dual level for forward and reverse. It has the silver tin oil splash plate. The engine is attached to the modern Mamod fully working tool station, which is colured in blue, and not the old lime green, used on the more older working tools.
