Mystery British Primer Caps

[GregN]

Hi all, I don't know hat exactly to call these. I was wondering what they fit on. There are too large for a 37 mm shell, maybe a 40 mm shell? What are the forum's thoughts?

I think these are 2pr primer protectors.

Hi
Yes
It's for 2 Pdr Cartridge

'To protect the primer cap a removable No. 30 cartridge clip is provided. The clip must, however, be removed before firing.'

Thanks guys, I have a 2 Pr., No.1 Mk. II N in my collection and the claws on the primer covers are too big. Can I assume that these covers fit on a non-naval gun?

Sorry GregN I didn't make it clear, the cartridge clip is for the 2-PR No. 2 Tank A/T gun. 40x304R
