A pair of Sissons vertical engines which couple together at the flywheel to produce a compound engine. Beautifully made, they are immaculate internally - outside requires fairly minor cosmetic work to produce an interesting engine. Complete with Pickering governor, each engine has a rather nice sight feed lubricator.
There's also a Sissons condensor pump included.
Height 48 inches excluding governor
Flywheel 38 inch diameter
Weight approx 12 cwt
