Very rare German smoke / gas grenade "Blendkorper 2H" developed in 1943 as an anti-tank grenade. It had a mixture of (inner tube) calcium chloride and in the outer capsule titanium tetrachloride when these two substances were mixed a nasty smoke / gas was formed which would force out the tank crew. These grenades are widely used and in addition are in glass so very few have survived. The plug was usually in cement or later in backelite and is missing on these grenades. Otherwise very good condition whole and nice. When ordering, the grenade will be packed very carefully. And
