Produced by Doll and imported and assembled in the USA by Bing in the 1920s. The engine runs on 110 volts.
I do not know the Model No.
The engine is all original except the chimney and safety valve weight.
It is a double oscillator (runs in both directions), but I only ran it in one direction during the video.
The water pump accessory is made by Ertl as a static model and has been modified by fellow Forum Member Bruce aka St Paul Steam.
