Need help identifying shell case

[points]

Hi guys and girls. Need help to figure out what this is. It's steel case and looks like 75mm. Can't get that exact as the mouth end is bdly warped. Looked all over the web and can't find anything close.
Thanks.

Navy 76mm?

Definitely Navy but I think more likely 3 inch now I have looked more

3 inch is 76.2 mm

Naval 3 Inch 70 cartridge case. 3 inch is the projectile diameter and 70 is the barrel length in calibres, 70 x 3 inch or 210 inch barrel.
