British No. 3 Mk II WW1 Rifle Grenade (P89-16)

WW1 British No. 3 Mk II Rifle Grenade

This is an example of the 1915 No. 3 Mk II Rifle Grenade. This model used a complicated wind vane assembly which was difficult to manufacture and not always reliable leading to simpler subsequent models. The spring clip (not fitted on this example) held the grenade in the rifle until fired when the collar would drop back allowing the airflow to unscrew the wind vane thus releasing the firing pin for detonation on impact.
