Strange Tool

What is this tool used for?

[Tmuir]

No idea, but I'm interested to find out.

I'm guessing it is for putting bends in metal sheet stock; a sort of narrow precision press-brake.

I believe that these might be used for repairing/refreshing the catch-lip(?) on pocket-watch hunter case covers. It seems I read that somewhere recently in my internet travels. Cheers.

I think I found the bugger but still don’t know how to use it. Says it is a Case Spring Plier. Second from the top of the picture.

The case springs for hunter cases can be quite stout, they are often held in by a pin once they are tensioned (sometimes a screw). To tension them in place you need these pliers, whether to remove one or install one. I am more familiar with the bottom two from the illustration, these press on the spring and the opposing side of the case. The one in the pic holds from the outside while tensioning the spring.
