Looks like some sort of plunger. On 1 end it looks like there is a finger pad connected to a stem. On the other end there are graduated rings along the side to secure it in place and at the end there is a circle in the center that opens when the finger pad is pressed down. Might be used for fluid control.
It could a primer pump for an old soldering iron gas tank(?) Can't remember the correct name. Sorry. Just a guess, thanks for posting great find.
Very cool solve. Thx all!
