Research Notes
With an estimated total production of 500 and fine finish, the Illinois Grade 104 is one of the most collectible Illinois movements from the pre-1890 era.
The grade was produced as an 18-Size Model 3 Openface movement with 17 Jewels and a Model 2 Hunting movement with 15 Jewels.
The 1882 S.F. Myers & Co. catalog describes the grade:
"No. 104, 15 jewels, expansion balance, 4 pairs, Nickel, adjusted to heat and cold, patent regulator, D.S. Dial. $36.98."
Despite being advertised as a 15-Jewel movement, the jeweled 5th pinion on the Model 3 variation results in a 17-Jewel movement rather than 15.
One of the primary differences between the Grade 105 and Grade 104 is the 105 features gold settings while the 104 is fitted with composition settings.
