[Daffodil]

Hi,
Wondered if the German fuze EKzdr C/28 was used only on naval guns or was it used anywhere else?
I've been looking for the answer and come to a blank..
Many thanks in advance ,

Thanks! I’ve got this one but it doesn’t have the acceptance stamp of an eagle over ‘M’. Do you have any idea why that might be ?
