You have one of the older style cameras which had a different gear head
than all the #10 cameras made after 1907. Jim Johnson in the chicago area
has a few, and might be able to help you,  and Bill McBride might have one,
and knows a great deal about them, or any other pan camera. The #10 ring
gears after 1907 and the #8 ring gears were interchangable, the difference
being the tripod leg size.Your problem is that the camera you have is
pretty rare, so finding a similar ring gear will be hard. Since there are
less moving parts, it should be easier to reproduce though. Jamie
