Slanted lid started in 1915, and except how the lid was constructed, remained the same shape on cars up to 1925 and TT (ton truck) to 1927. That switch was used from 1915 to sometime in 1916. The 1917 model which started in late 1916 used a pressed steel cover instead of the composite material body and inset switch face. There may have been some overlap in switches between the end of the 1916 brass radiator cars and what we call black radiator cars(1917 models) starting fall of 1916.

Without a front shot of the coil box, can not pinpoint the dates of use, but guessing into 1919.
