Here's a couple of pics of an old timer I took out of a factory a few months ago. It was used as a Defrost timer on a Freezer.
Here is the outer case, made of Cast iron.
Here is a shot of the nameplate of the timer, sorry about the poor quality of the pics, it was pretty dark where I was working at the time. I had another shot of the inside of the timer enclosure, but I must have accidently deleted it Darn!.

Trumpy, these time clocks were used in abundance in the UK one area they were used in was street lighting columns you would find a clock in the bottom of each lamp post. Still lots of them about even today.
