Hz 05 schr question , something unusual?

[AKON_]

Im maybe missing something , whats this for?

Hi AM 16
According to the archival names of documents... which are publicly known, it is still necessary to include in the list of types H.Z.05 a type with the name: U.H.Z.05,, what is the meaning of the letter U - I do not know yet.

I'm not sure if these pictures add anything to the conversation, but the one on the left is unmarked and the one on the right is HZ 05 Schr

U means Unterricht

Those U Fuzes are inert. Additionally to them there were "U aufgeschnitten" models which are factory made 1/4 cut sections.

Hi Alpini
That's interesting. Hopefully, a drawing with this designation will be found later... which would support and anchor that opinion.
other designation:
H.Z.05 Sch. o.V (ohne Vorstecker)

Hello,
Nice Fuze!
If the brass plate is smooth, without a bar, then it's indeed the same as this one.

Thanks also to Bernard Delsert book for the photo.

I confirm what Alpini said.
There are also the "EX" or even the "ersst"
