A. Model K31 1/2. (sometimes called a 'bathtub' time lock due to
the shape of the brass case housing the combination lock). This time lock was made early
in the production run and was designed specifically for use in a freestanding bank chest
designed by the Hibbard-Rodman-Ely Safe Co. of New York, NY (later the Manganese Steel
Safe Co.). Each lock contained two Seth Thomas made 72 hour movements along with a four
tumbler combination lock. The safe contained a pair of these so as to encompass two
combination locks and four (two pairs) of time locks. Production runs for this lock ran
from 1902 through 1911. Of a total of 1500 to 2000 of these locks made about 100 of these
locks are now known to survive; fewer than 20 in sequentially numbered pairs. Movement
