1926, Fuller & Johnson, Model NB, 1 ½ H.P., Hit-and-Miss Engine
This is one tough, little, well-running engine... and very heavy! Notice the two silver-colored spikes mounted on the side of the wooden rail. They'd be removed and inserted into the wooden rail's holes to anchor the engine in place on the ground. There are two more spikes in the same position on the other side of the engine.
