I recently purchased this panel on e-Bay. It was listed as a “US Army Pre WW2 Gun Control Panel.” I got it because it is labeled “Federal Laboratories Inc.” The seller had no idea what it was and, as you can imagine, typing in “gun control panel” on Google, yields somewhat unhelpful results. The only thing I can think of is something I saw advertised in a reproduction 1934 FL catalog. It was an internal tear gas distribution system. If a bank was being robbed, or a prion riot was raging in the mess hall, a bank teller or prison guard could apply pressure to a foot pedal, and then the room would fill with a fog of tear gas (see pictures below).
Has anybody ever seen a device like this? Am I even close, or am I waaaaaay off? The panel measures 9” wide, by 14” tall, if that helps.
