This is a true barn find and a historic electric motor. The Manufacturers mark is cast brass and signifies that this unit is from 1892 to 1894. Is was run from a battery or bank of batteries. Is has 6 armature coils, and 2 poles. It moves and spins freely. I have not tried to run it and I expect it would need to be completely refurbished. It also appears that the brushes are missing and may need springs. Please feel free to contact me with any and all questions.
