Hi all. Came across this shell case. It appears to be a shorter version of the French 75mm. It is closer to the length of a German 77mm case (to the right for comparison). Primer looks French but there are no discernable markings except two small one which look like they could be oriental, but may just be the remnants of some other markings. If anyone has any idea what this case is for I would be interested to know. Many thanks.
