Rider-Ericsson: Rider-Ericsson Engine Co., New York

摘要

Additional info: The unusual thing about this engine is that there is no information listed for a 4-inch Rider-Ericsson engine in any literature. This engine was manufactured in England and is machined with Whitworth threads. This may have been manufactured under license, or was it a one off model? It's a very nice running engine. It is a hot air engine, which is quite different compared to a typical hit-and-miss engine.
