I have this plug. Used I guess to protect the opening in shipping or moving
projectiles. I have 8 marked brass discs for same. If any one is interested in the 8
pieces contact me. One has the Broad Arrow on it. I don't know anything
about them. When the wing nut is tightened it squeezes the rubber grommet
which expands and seals the hole.
