Does anyone know what this is used for?
Cannon pinion closer. You are missing the pin that goes up through the bottom and inside the cannon pinion to keep from closing it too far.
I have a "modern" version of this tool, but I love the look (and age) of this one. I will probably never find the pin, but I'm going to hang on to this, nonetheless!
If you happen to have a smoothing broach of the correct diameter, you can use that. Or, a sewing needle.
