A. Model #6, (later no. 6201), c. 1910. This model was produced in three slightly different sizes from 1900 through 1929 with a total production of about two thousand. Fewer than 75 of the model #6 exist today. This example is in superb condition; it has the rarer push-button door release as opposed to the small hand-cuff style lock. Case #303, movement # 2884. From the Italia Bank on Broad Street in South Philadelphia.. The last picture shows an advertising plaque for the #6 on a dummy box above the actual time lock. file 88

B. Combined time lock and combination lock (timebination). Purpose is the same as a time lock, but designed for short duration. Dual movements, 5 to 30 minutes maximum time delay in 5 minute increments. A small pin is screwed into the hole corresponding to the desired setting time. From a York safe. For an example of a combined key lock and time lock see the Mosler example. Another example of a modified time lock to deal with shorter inter-day time intervals is a small Yale make. file 96a

C. Model  6280. A modern version of the 6200 series. In the later half of the 20th century many manufacturers cut costs by dispensing with the metal door and replacing it with a screwed on plastic cover; often with integral lenses for easier reading of the dial. c. 1950's or later. file 60
