This was in a mess of parts, looks like it lines up with the manifolds so I assume it is some kind of boiler, heat exchanger, Frankenstein add on to the right side of the motor. Fancy brass petcocks, may look good painted/polished but wouldn’t know what to do with it.

Accessory manifold add-on with priming petcocks.

Thanks for the opinion. I guess if it was real cold and hard start would help to prime it with warm gas to fire. Not worth adding it on for me, but don’t throw nuthin out. Another dust collector.

You could always offer it for sale and then buy something you need.

The petcocks might be handy but it is a heated manifold to aid in fuel vaporization. In warm climates with hot temperatures it may warm the fuel charge a bit to much. It would be good for cold climates or maybe some old Pietenpol Sky Scout airplane engine.
