Yesterday I was at Shrivenham wandering around their weapons hall (as one does) and noticed a complete round of 4.5 inch Mk 8 naval ammo. Fixed ammo, but with the deep annular grooves around the neck...so I'm thinking that my case originally had such grooves but they were flattened out by chamber pressure on firing.
I'm returning next week with a camera and a tape measure....
