Yale & Towne Manufacturing Co., Stamford, Connecticut - 3 movements, Type Triple L, v.2 mounted to Yale No. 2 bolt motor

Model Triple L. These locks used the medium sized Type L movement by Seth Thomas and were by far the most common sized of the coffin style movements used by Yale and this model had the largest production in the Yale line. The model L was used with automatic bolt motors so no bolt dog-work was in the case; only the release levers within the bottom bulge of the case to actuate the bolt motor. This example is mounted to a Yale size #2 bolt motor. It could also used on smaller ot larger Yale bolt motors, as well as bolt motors from other makers. Case #3734, movement #41182, #42288, #44778, Yale bolt motor size #2, s/n #85 file 354
