I saw a news article about an exhibition of items confiscated from students by a London teacher over 15 years of his career.
In some photos of the items I noticed some cartridges. Before anyone says it, no, they weren’t mine. I was able to find a close-up on another site via google images.
The item on the left looks to be a .55 Boys WII Projectile. The middle is almost certainly a spent 7.62 Nato case. However, the round on the right has me wondering.
It could just be a dug up 7.62 Nato case with some sort of corroded RN projectile. However, to me it looks like it could be smaller calibre. Now I want to see the headstamp.
