Model Vertical Steam Engine
A large two cylinder twin flywheel engine by the German maker, Doll et Cie. The dimensions are 21" to top of chimney, 6 1/2" x 8" cast iron base, 5" twin flywheels. It weighs 16 lbs. The engine has apparently fallen over one or more times and has some old solder repairs of external parts. The sight glass is missing, but a valve at both top and bottom of the glass allow the engine to run without replacing the glass. The flyball mechanism is missing from the governor, but the governor shaft and gearing are present. The governor was for show only and didn't regulate the engine speed. Two steam fittings need to be soldered - the inlet from the water pump and the pressure gauge.
To test the engine, I removed the water pump inlet and held a finger over the hole in the boiler while pressing down lightly on the pressure gauge and holding an air hose against the upper water level valve. The engine ran well under low pressure (approximately 10-12 psi). The whistle also works well at that pressure.
While I've never seen a two cylinder Doll with twin flywheels, I have no knowledge of the rarity of steam toys, so I hesitate to claim this to be a rare engine. My guess is that this large engine was expensive and likely much less common than the smaller engines.
