Large Shell Case from Normandy

[garys39]

Just received a few more shell cases (and assorted items) from my friend in Normandy, 2x of them are very unusual, never seen them before in my travels and purchases from Normandy, anybody care to guess what they are ? Pictured next to a 6339st and US 105mm case, for comparison.

This is a bad question with insufficient data.

Length of shell case ?
Neck diameter ?
Rim diameter ?

The diameters of the unknown casings look to be roughly twice the diameter of the mouth of the 105mm casing.....Naval round?....What type of guns were mounted in Normandy's bunkers?.....Bodes

Thinking again, I believe some were rail guns.....Bodes
