Here is a clock I bought in a Richmond jewelry store,many years ago.

the first picture looking up from the weight.

this is the simple movement.

Here is the whole clock.. less the hanging weight.

One more..

Stephen,

Was it new when you got it? My brother got a similar one in the early 1970s that was plastic, a kit by Lindberg, I think. They started making a lot of these after the 1892 Columbian Exposition, but the ones I have seen were all wood.

Does it run?

Andy,It runs sporadicly,and never for longer the 15 mins...needs constant adjusting.

It was,I'm told a reproduction from Germany,hand riveted etc.

Interesting clock Stephen, i have not seen others like it.Is it mostly made of some kind of metal?

I have a couple of the "Columbus" clocks. They were, as mentioned, wood or plastic. I will post a picture as soon as I get a chance. I'm sure most have seen these before.

Kevin,it is a soft metal....I assume Iron.If you look closely you may see what looks like slag.
