I was thinking about how grenade Grenade launchers were relatively rare in UK in the 1980's. It would be really cool to work in some old flare/gas grenade launchers maybe with home made munitions??
No.1 Mark 1 flare, tear gas gun:

Smith and Wesson 210/276:

One of these would be an interesting "ENIGMA" weapons to have in the game for to add a little color,flare, smoke and gas into a game.
Oh or how about a Martini Greener Light Harpoon Gun???? Those have always really got my creative juices going.

Just some weird ideas about some old stuff that might turn up and or add some pin ache to the weapons that might be floating around.
