77x118R Casemate gun case

[charley777]

Also in the same book referred to in the previous thread ( 77x383R case ) is this drawing.
It shows a 77x118R necked case for a Blockkhaus gun.
This is also not to be found in any of my lists.
Any opinions or observations most welcome.

This is also not to be found in any of my lists.

It may be because it's a normal 75x118R case for Krupp Mountain guns. We discussed this case already several times in the BOCN I think.

OK thanks Alpini
I did wonder about the possibility of it being the same case...
