Feeder?

[treshkin]

Please, help me to identify this "cartridge".
Looks like .303 British feeder for MG drum or Mag.

What is it and for what weapon?

It is the follower for the 100 round Bren anti-aircraft drum magazine. The one for the 100 round Vickers GO is similar but it does not have the top loop.
