380 rev pyrotechnic or flare?


I pulled the 1 inch long orange paper/cardboard tube out of this .380 ( at 6 oclock) headstamped round. Tube is tied on end inside the cartridge. The end that is exposed has a hard brown resin inside tube that was covered by a thin black film. Cartridge had only a small amount of powder in it. Can anyone tell me about thie pistol cartridge. Who made it and when? What was it called a flare or pyrotechnic?
