Hi Mike, That is a real interesting and unusual find.

Weeden comes to mind with lead cylinders however not even closely related to yours.

If you get a chance to pull the steam chest cover off, I would be very interested in photos of the internal rigging.
None I have seen have the valve rod going into the steam chest that low.

Congrats..!!!
