This engine was designed and built by H. J. Coventry, an Englishman of some renoun, probably in the late 1930's or 1940's. This is in the "Golden Age" finish.
LATE NOTE: Reluctantly, I have sold this engine. I am giving up on building a boiler with the current stringent, difficult and impossible requirements of the State of Washington. I will be disposing of most of my Steam engines.
