I have attached a picture of a drill/sub-calibre round (suitably modified so it is not fit for purpose) which I am trying to get more information on. It appears to measure 57mm as a projectile and what would be the case length is 360mm. It is clearly German made, probably for Turkey, but I cannot find reference to any 57mm cases of that length. Anyone any ideas? Can anyone translate the writing on the base?
Many thanks
