Hello, I recently purchased this E Howard clock but am unsure what it really is. I am guessing regular electric as the wires look too large for 3 volt as in a Self Winder. Could it be a slave, but it seems to be a stand alone clock since it has coils. Not sure I see a winding motor or a spring. Also wonder what the lever on top is for, it goes to a pull wire sticking out the bottom of the case.Not knowing much about electricity, I don't want to just plug it in and see what happens. Other E Howards seem quite collectible and of good quality. Does this one fit in that category? Age ideas?It has a nice looking 18 inch wood case and decent dial. (minute hand upside down in photo) Hands a little rusty, steel wool and paint? Thanks so much for any information and guidance.
