Sargent & Greenleaf, Rochester, New York - 3 movements

       A

     B

A. Model Triple B, version 3. (later no. 6305). c. 1930. Both locks on this page (A and B) are the same model and share the same type case. A model could be produced for a very long time as these two locks illustrate. This locks' components are all from the same period (post 1930's) Version 3 has the snubber bar below the dials as opposed to versions 1 and 2 where the bar is above the dials. Also by this time the time movement's positions were interchangeable where they were not in versions 1 and 2. Case and bolt # B-2033, 'L' sized movements #13935, #9110, #14545. file 94

B. Model Triple B, version 2, c. 1890's. Note contrasting colors of the movements, case and the various components. I believe this was done purposely for aesthetic value. Normally a silver case would be fitted with silver movements. Case # 84, consecutively numbered "L"-sized movements, #663, #664, #665. While the design used modular time movements as with the early Triple A, the movements were not interchangeable, and each had it's specified location. One can usually see scratch marks made by the installer on each movement I, II, III indicating their order. file 32
