I am looking for some help, my grandfather passed away leaving his 1915 studebaker six. I am looking to take the car and learn as much as possible. First is there is some confusion on weather this car is a 1914 or 1915 year car. The serial number on the door is 500735. The gass fill is on the dash on the passenger side. The next big one for me is, was this car a brass car or nickle. I am trying to learn as much as possible so hopefully one day soon I can drive the car. Any information will be greatly appreciated. Thank you!
