According to David & John Erroll’s book, “American Genius, Nineteenth-Century Bank Locks and Time Locks,” The manufacturer Yale and Towne only built 13 of these locks, “Yale offered a Type DD and Type EE, combining two Ds or Es in concert. While none of these is known to survive, records show that Yale did sell three Type DDs in March 1890 and thirteen Type EEs between November 1889 and December 1891.”
American Genius, page 246.
The Lock here offered is a model EE and has the serial number 13, see picture #16.
This 72 hour safe-time-lock is equipped with six American Waltham Watch Co. pocket watch movements size #14, model 84. The cluster on the right has the movements with the serial numbers 4’527’406, 4’527’408, and 4’527’409; the serial numbers on the movement-cluster on the left are, 4’527’318, 4’658’574, and 3’509’511. The movements in the cluster on the right seem to have the original movements with consecutive serial numbers, the cluster on the left seem to have some of the movements replaced. The damascening pattern to decorate the movements is called “Hillside.”

This robbery went down as the biggest in US history.
