WW1 GRENADE LAUNCHER No1 Mk1 of 1917

Mentioned first in 1917 for use with a No23 type grenade, fitted with a gas check plate and designated the No36 Grenade See Item A0809. The plate is required to contain the gases from the blank cartridge in the rifle, thus pushing it out of the cup releasing the grenades clip (the pin having been removed).
