Great Uncle brought home Trench art from Verdun with a Lorraine cross. Markings are 75 DE and A RS /333. 15. There are 5 punch marks and what looks like a small K near the primer. Can anyone explain the meaning of the marks?

Quite a bit of information can be gleaned from the description here (though a photo and measurements would still help greatly).

  • 75 DE --(is there a C following this? and what are the dimensions?) points towards a French 75mm shell, perhaps used in something like this
  • A.RS --was identified in the answer here as 'manufactured in Rennes (Ateliers de construction de Rennes).'
  • /333 --likely a lot number, as per discussion here
  • .15 --is the year of manufacture, 1915.
  • five punch marks and small k near primer --unclear, need photo for context

Most of this can be compared to the answers about a similar shell in What can I learn from these WW1 shell cases?

A discussion on the greatwarforum has info concerning the 75 DE C designation.

ARS is also mentioned in the headstamp codes listed here

A discussion on marking on similar 75mm shell casings can also be found at forum.cartridgecollectors.org
