I was looking (and bidding) on that car. It is the same model as the Edison car at the Edison National Park. I was just going to leave that car as it was except maybe try and find the missing lights. That car is as original as original gets and I especially love those solid tires. I have a 1914 model 43, a 1917 that I forget the model right now and a 1922 model 90. The 22 and the 17 have had the interiors restored, the 14 is original but in no where near as good a shape as your car. I have had the motor on the 14 rebuilt and Rhode Island Wire rebuilt the wiring harness and I suspect your harness is the same. As previously listed the electric vehicle museum is a great source of original documents http://www.electricvehiclemuseum.org. The electric vehicle newsletter is good to see and if you haven't had contact with Galen PM me and I will get you his contact info. He had all of the documents that are on the museum site but he doesn't run that site. I have worked with VEVA Vancouver Electric Vehicle Association, they are working on their 1912 Detroit. They have a resistor pack for sale and they have remade the copper plates for the speed controller
