I can identify one thing for you. The box contains tear gas cartridges cartridges for a pen that discharged them, also shown in the pic. The cartridges were .38 Special caliber and the pen was a single shot. You pulled the lever back till it "set" then used the trigger button to shoot it. I had a friend who was a bartender and one night a girl walked in, opened her handbag, withdrew one of these and said she had bought it that day. Ray asked her, "How does it work?" She said, "Like this," and fired it off. He said that they had to empty the bar, call the fire department, and ventilate the bar for an hour to get all the gas out. I would guess the pen gun and cartridges would bring $50-$60 to someone as a collector item. Modern day pepper spray and Mace have made them obsolete.
