This is a good example of a Sargent & Greenleaf model No: 2 timelock, circa 1890. {The model No: 1 being a combined combination lock and timelock in one case. }

The example shows the decorated drop arm and case, which later examples lack. It is a dual movement { on one plate } 72 hour movement. The case is missing it's original lock and is somewhat battered, but the internal mechanism and movements are in good order.

My thanks to John Errol for his assistance in dating this lock.
