OK 88 kwk 43 , first thought Tiger II.
But that date is '43...
As I understand it there are 2 different case types/shapes....
One for the Pac 43 and one the kwk...
if correct as I understand it again the kwk was mounted in the Elephant but not the Nashorn or JagdPanther...
So therefore a date of '43 makes it a Elephant round...
Or is it one round fits all... but again the date says no the Tiger II...
Ok it may have found its way to a Tiger but when produced they where not..
