Also interesting was the fact that the majority of these model 9's, about 2400 of them, were made between 1913-1915 and then 3 years later in 1918 a single run of 400 with these special Double Roller markings were made. An interesting and beautiful time piece there, thanks for sharing it.

Great watch! I have a soft spot for these particular model 9 Sangamo Specials. This one has the two screws facing down to hold the balance jewel. Interesting because they started production in 1913 this way. Then changed to "screws up" and then back again for this last run? You can see other samples and variants in the IHC185 Illinois Watch Company Research Forum.
