Both A and B. Type K22. Both A, B are the same model using identical 'L' type movements, the second smallest made by Yale, but with different metals used for the case and associated bolt mechanism. The color of the surface as well as the treatment used on the surface (plain, or some variety of damascene) would be chosen to compliment surrounding vault door mechanism. The second bronze color case had what Yale called their "bronze wave" design. The L sized movement was the most popular size ever introduced by Yale. The 'L' sized movements numbered after 5000 were made by Seth Thomas after E. Howard exited the time lock business in 1902 and are often confused as being made by E. Howard because the two looked very similar. 5"w x 4.25"h x 3"d. A - case #682, movement# 28388, 28389; B- case # 869, movements #38544, 38672. See this lock in situ on a Diebold safe door below B- file 45

C. Same as examples above but with later movements made in Switzerland from the1950's. This case is slightly earlier than the one illustrated in example A and would have originally had those type of Seth Thomas made movements; also features a less common right-hand hinged door. Case # 624, movement #62906, 62907. file 125.

D. Type T221. c. 1900 -1920's. This lock was developed in response to the need for a smaller time lock to fit into a more compact  emergency safe doors, chests and yet still used the same L sized movements as in the three examples above. 4.25"w x 3.5"h x 2.5"d. The movements and dials are consecutively numbered 33536 and 33537. Case #213. file 108

E & F. Model K22L. c. 1950's. Two versions of the same model. Picture C is OEM with contemporary movements from Switzerland while B has been retrofitted with earlier style Type L movements. Original K22 version from the c. 1910. file 29, file 37

Below a photo of a pre 1900's vault door with a Model K22L fitted onto it. In the second photo below, notice the large space in the door around this small Yale time lock. The door was designed to accept a variety of time lock makers. One can see other makes in similar sized Diebold safe doors: Diebold Type 1, and Sargent & Greenleaf Model Triple A
