Original German gas bottle that contained toxic gas to be used in chemical warfare during 1917. This green glass bottle, 7.5 x 1.75 inches, contained a fluid with a color varying from eggwhite to brown/yellow and a smell similar to shoe polish, it was known to the Germans under the code name ‘Clark’ which stood for DA-gas, a Vomiting agent. The product was meant specifically to penetrate through safety measures such as gas masks, treated cloths and even the anti-gas ointment. It was only loaded into projectiles of the 7.7cm model 1896 and the model 1915. These could be identified by a blue cross on the body. It was loaded into projectiles and when the shell exploded the glass was shattering and the fluid vaporized. Recovered in Belgium. More glass caps are offered elsewhere in this auction.
