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..!!!

Hi Gil,
I attempted to take the cover off the steam chest and the studs were coming out with the nuts and one stud was stripped out in the valve chest, so I abandoned the operation. I’m not going to disturb anything else unless I absolutely have to.
The slide valve rod does enter at the centerline of the valve chest, though.
