I just wanted to thank everyone who identified this as a GJG. It has been fun doing the research and having so much help!

I recently digitized my family photographs, including this one of my grandfather chauffeuring this tourer in San Francisco. The back of the photo reads: "Happy New Year, Jan. 1, 1912. In addition to the overall shot, I zoomed on the wheel bearing cap to find any clue as to the manufacturer. I have eliminated many of the common 1911-1912 cars but still can't find this one. Any suggestions as to what it is? Thank you, in advance for your help.
