I came across this today, it looks to be more unloaded than fired at some point.
Interesting that the base stencil is still present, odd maker mark, well to me at any rate.
Anther casing I likely won't fill ~

This maker may be the one ; C. Collins Cartridge Company in Birmingham.
My four casings, a great shortage of projectiles for these over here.
