MK-13 Smoke and Illumination Flare

The MK-13 held two types of signal in a 1-½-inch x 5-¼ inch cylindrical tube and was a component of pilot survival kits / life preservers. It contained orange smoke for daytime signalling whilst the opposite end held a pyrotechnic flare for night illumination. Paper caps covered the ignitor ring pulls on each end.
