Hello, I found this on the Thames foreshore in London and am trying to ID what it might be. I think it is brass and 7cm across, and from the shape I'm wondering whether it is from the front of a small bomb. It's from Docklands, so there were certainly enough of them which fell round there.
I'd be very grateful for any ideas, even if it eliminates this as an option.
Many thanks
