Ernst Plank, ca 1895
I have had this engine for some time, not knowing what it is. I had recognized the engine frame as being Ernst Plank, but was not sure about the rest, whether it was a homebuilt made on spare parts or if it was original. What puzzled me was the governor which looks very primitive. I gor a happy surprise as I browsed through some books and found the same governor on another Plank engine, so I tend to think this machine is actual an original, probably dating from pre 1900.
