In my collection of vintage cleaning gear I have two objects which are puzzling me.

The first is a .22 steel(?) jag like thing which tapers to a sharp point and has a spiral thread all the way to the base. It has the standard PH female thread and mates(!) neatly on a PH rod. It isn't one of those plug things designed to push a circular patch through from the muzzle end. I wondered if it was an armourers tool designed to snag out a jammed patch?

The other is a simple brass rod with a PH male thread which mates neatly with any .22 PH brush or jag. I bought it in a lot which also included the screw thing, but the two are not necessarily connected (pun intended). It seems too short to serve any useful function?

Has anyone any suggestions, polite ones please. Indeed does anyone actually know what they are supposed to do?
