B. Model ? Uses the largest style movement made for Yale by the E. Howard company, designated 'M'. This size movement made and signed by E. Howard are fairly rare. The Howard movements had the 'M' designation on the dial. Only 200 of these large-scale movements were made by Howard before they went out of the time lock manufacturing business altogether. Nearly all time locks using this size movement were equipped with later Seth Thomas equivalents that looked nearly identical but lacking the Howard signature logo on the front plate. file 104

C. Model K3L with consecutively numbered Swiss-made movements. The movements were manufactured for and distributed by Herman D. Steel, Co., Philadelphia, PA. and sold to Yale. 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 57

D. These are largest and smallest size movements Yale used in their popular 'coffin' style design; designated 'M' and 'T' (massive and tiny?). These movements were made by E. Howard, however, Seth Thomas also made movements as exact replacements. Yale's most popular size, known as 'L' is midsize between 'M' and 'T'.
