Sargent & Greenleaf, Rochester, New York - 3 movements, Model Triple B

A. Model Triple B, version 2, (later no. 6305). c. 1893. 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. 72 hour dials with no company name. 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 see scratch marks made by the installer on each movement I, II, III indicating their order. The case and movement numbers indicate this was early in the production run of this model. Case and bolt #84, consecutively numbered "L"-sized movements, #663, #664, #665.  file 32

B. Model Triple B, version 3. Pre- satin bronze case with rarer 'crystalline' damascene surface rather than the more common spotted pattern. The scalloped glass opening was a short-lived design. Version 3 had the snubber bars moved from the top as in Version one and two to below the dials. Also the movements all became truly interchangeable where they were not in the first two versions. Note the surfaces of the snubber bar and drop bolt have plain surfaces indicating a date sometime after 1920. Later fitted movements of silver color rather than brass that would have been the original matching color. Note the style of the enamel dials; they have a rare extended 120 hour duration with the company name and Rochester, NY. Case bolt #B-787, movements 1-1548, 1-1535, 1-1545 (much later serial numbers). file 106

C. Model Triple B, version 3, c. 1920. Both locks on this page (A and C) are the same model with 72 hour dials 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) 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. 72 hour dials with Sargent & Greenleaf, Inc. Case and bolt # B-2033, 'L' sized movements #13935, #9110, #14545. file 94
