These are Mosler time lock movements from the 1930's to the present day. The left one is an Illinois movement. The left center is a Waltham movement. The right center is a Recta Swiss movement. The right one is a present day movement. This is a complete history of time lock movements from Mosler Safe Company, who is no longer in business. The Illinois and Waltham movements are rare. They are all for sale because I am downsizing my collection.
