My research tells me this is a E. Howard Clock, model #3 and was originally installed in 1900. It is not behind the clock face, but works quietly in a protective room in the tower, about 50 feet from the clock face.
Now, the mandatory description: This clock is a vision of many circles, upon circles. In the center is mounted the sweep hands (arms?) heavy and Victorian fancy, with pointed ends.
The face itself is 4 circles out flowing from each other..the outer ring is nothing, the next two rings, moving inward, hold a lot of dots. Dots that mark the minutes/seconds of every minute and hour and day.
The quarter hour, traditional hashings, are set with Roman Numerals.
