Re: Weapons Locker
Memory Alpha mentions it.
In "Hard Time". . .Chief O'Brien opens a locker and some letters can be seen on the inside of the lid; those letters were not made unreadable. On the screenshot to the right (turned 180 degrees and mirrored), the words "Action Packer" are legible. In real life, "Action Packer" is a line of storage containers by Rubbermaid.
