This steam turbine may have come from a steam shovel. The output is given as 40 Amps at 32 Volts when turning at 2800 RPM. The unit is large, about 30" in length and weighs.....a lot!  It spins freely and has been tested with compressed air.  The alternator looks complete and although dusty, appears in workable condition.

Part of the govenor is missing and believed to be deliberatly disabled as it is a wastegate type which can vent a lot of steam.

Asking $700 obo.
