Help with german fuze

[MINENAZ16]

Hello,
Is it a variant of the german artillery fuze K.z.f.Spgr.m.K.u.St. ?
The common model I know is not truncated on top.

I don't have the german name (yet)
(Form Artillerie Allemande - Les fusées, available on Gallica)



Cheers,

S.

Thanks for your answer.
I also have this ambiguous drawing showing both head (cylindrical and truncated). Both fuze exist, so I assume 2 variants.
Ww1 British doc and french books (Belot) show only the cylindrical model (with optional cone on top).

Kz. f. Spgr. m. k. u. St

Does anyone have a picture and information on the Kz. f. Spgr. m. k. u. St? See attached image. Joe

I'm not sure if these provide anymore help but a side by side comparison
