Thank you for posting the photo and others. Note the shiny paint job on both Fords. The 1915-16 appears to have the radiator painted black -- probably to make it look more modern.
The black radiator car has the later unequal length windshield hinges so the photo would have most likely been taken sometime after Apr 19, 1917 ref: http://www.mtfca.com/encyclo/doc17.htm .
APR 19 Acc. 78, Ford Archives
Windshield hinge (with the unequal length arms) noted.
From the photo I cannot tell if the wishbone is above or below the axle on the black radiator car.
