What a beauty, obviously had a very good restoration. My first thought was a bit over anghious on the price but that restoration work should be worth something.
I'm going to suggest mid to late 30's manufacture, looks like a factory instaled electric drive replacing the overhead gang steam belt drives of before 1934.
That would fit quite nicely on a bit-o-floor space i have left beside my 1916 Hendey..but alas, finaces wont allow it.
