This is an exceptionally interesting clock- movement looks to be Salem Bridge type, though there are no pictures that I can find. Does yours have a Pennsylvania label? Case looks to be a typical Connecticut wooden movement case, maybe bought in and mated with a Pennsylvania made Salem Bridge type movement. Can you post pictures of yours, for comparison?
That certainly is a most interesting clock which sold at auction!
What caught my eye was the spacing of the winding holes.
A bit of research turned this up:

By some miracle, I was able to access the article and rather than getting the endless malfunction resulting in a repeated prompt to log in.
Scroll down to page 479.
Pictured there is what I would refer to as a "glorious fragment" of a very similar clock minus the dial and spat.
The case is a CT style carved 1/2 column with carved paw feet in the front and which probably originally had a carved splat.
There is a mirror in the door. Don't know if it's original.
The movement is a Salem Bridge
style brass weight driven movement. It is not believed to be of CT manufacture.
The label is shown with the place names of Boonsborough and Hagerstown, MD.
On page 470, a pillar and scroll style clock by A. Johnston of Hagerstown, MD is pictured. Very similar Salem Bridge
style movement!
PAN's ? about evidence of a PA origin is actually quite on the $$.
Now, Salem Bridge s
tyle movements are known in PA clocks. Well, apparently Hagerstown is 5 miles from the PA boarder, Boonsborough is 10 miles further south!
PLEASE post pictures of your clock including label and movement.
Potentially a very interesting clock indeed.
