Ok guy's here it is.

The tool was issued only to the production line workers who bleed the brakes on the new vehicles as they rolled down the line.

The tool is a Proportional valve tool. It keeps the plunger from moving while they bleed the brakes as it moved down the line. It held the plunger in the center of the proportional valve. I have never seen one until this one. My friend gave it to me as a gift. So now you know the rest of the story!
