So, any of y'all old-timers recognize this? It's a home-made bullet luber. There is a nail between the two shells that runs through the primer holes. A flat piece the diameter of the bullet is silver soldered to the end of the nail inside the top shell. Bullet wax is melted into a container and bullets placed into the wax. When the wax solidifies this tool is pushed down over a bullet, the bottom shell is pulled apart from the top which creates a vacuum and pulls the bullet from the wax.
