This heavy duty antique pressed steel and cast bronze miniature steam engine model is pretty good sized, the base it is on is about 9 1/4" long x 7" wide and the boiler is about 7" high x 2 1/2" in diameter. The steam engine is extremely sturdy and well built and the brass plaque on the base reads ELECTRO Steam Engine Made by the Electro Mfg.
The cylinder, drive shaft, and flywheel appear to be made of cast bronze and the base is made of thick pressed steel. The boiler, tubing, and other parts look to be brass or bronze also. This the only electric powered vertical boiler I have seen and I believe the 4 pound model could have been made to be used in an industrial engineering class room context as opposed to a mere child's toy. There is some tubing that is gone and I don't have the electric cord but what is there is in good, straight original condition.My best guess as to age is ca.
