Does anyone have some pictures of the clutch properly installed in the minute shaft? I received one for repair and the minute hand will not advance. Discovered the clutch spring is missing. My somewhat faulty memory tells me it goes on the back of the minute shaft with a small bushing.

I'm not familiar with that movement but there is a lot of info in this thread.

I think that's a popular design. (The spring behind the gear w/ a collet.) I would think that many of the Seth Thomas movements would have a similar design. If you can find one to look at.

I don't have anything on a Seth Thomas 120F but here is the clutch assembled and apart from a 120-L and 120-J, I would expect the 120-F to be essentially the same.
