50mm grenade launcher 1917

This French 50mm grenade launcher was fitted on a wooden shaft with metal components.
It fired the early
DF 1917 hand/rifle grenade which had a propelling charge in the base of the body.
The striker was cocked and fired by a metal handle, coming out of the side (similar to the ww2 british 2" mortar).
It was adjustable by rotating the barrel in or out of the launcher base.
