Militery objects to identify

Hello .
I found three militery objects at hill 113 south israel.
In that hill fierce battel took place between idf and egypt army in oct 1948.
Who can help me understand what was these objects.

These do look much like remnants of British time fuzes for artillery projectiles.

The alloy item with large hole through the middle is a centre tube from a British M36 hand grenade. Other item with threads either side of a collar looks like a fuze for a British 2" HE mortar.

First image, first item on left - almost certainly a Canadian manufactured, British No. 119 artillery fuze. Filled by General Engineering Company at their Scarborough plant, Canada.

A cleaned and clearer image of the markings on the second item, would make identification easier.

Thank you.
