I have only seen photos of this case.
It measures 75x277R ....no idea of rim diameter.
And it looks as though some of the case might be steel....
Though it may just have been dipped in phosphoric acid or some other metal cleaner (?)
A common size .but in the headstamp is 75 DEC which i would have thought would be for a 350mm long case.
Can anyone tell me about this?
Did some 75mm De Campagne guns use a shorter case?
Thanks very much
