Badge, Bullet Casing, and Not Sure

[fakeer]

Found some type of badge with SIA written on it. I think "club" is written on the bottom right.




Also found this bullet casing with L2A2 written on it.





Finally, found this fishing weight looking thing, but not sure what it is.

I'd vote that's a fishing weight. Not sure on the age of the casing, and the badge SIA might translate into something.
Maybe this.

L2a2 could be 1950's - 1980's surplus .308 ammo. It was made by several countries with that marking.
