As far as I know LSprM were dropped too so this fuze could be a version made for 7.58 LsprM.
On fuze K.z.11 are some markings on the sides,or only on the bottom?
I think this is a very interesting option
Here is an example of a German 25 cm s. Spr. M. fitted with fins and used as a bomb. (Note the bomb fuze)
Note the bomb fuze
Hello Pascal,
The fuze on the 25 SprM used as a bomb is different. It's the same steel fuze used on the Puw 50.
I'm quite sure the fuze shown by trrr is for a 7.6cm dropped. I saw such a round with a tail screwed in place of the brass primer on the base.
