I can't find another instrument like this, for some reason it makes me think of some kind of electric generator or engine, similar to some early magneto devices. But I just don't KNOW. It measures about 10" x 4 1/2" at the base, there are parts that stick out further.
Weighs over 15 1/2 pounds as it sits on a solid cast iron base. Shows some wear and soiling. Please view all twelve photos to help judge condition.
