Hz 05 schr question , something unusual?

[ArtilleryManiac1916]

Hi everyone , so recently ive dug out this Hz 05 schr , manufactured by Sb in 1916 , ive had 2 speciments already , the early classical with 3 screws and central hole in the bottom , and late war zinc-steel 05-17 .

So whats unusual , the geometry of bottom cut lines on the sides at diffrent angle , and 2 screws where missing , as well as central hole for the tube ?.. , is this somesort of inter variant in the production ? It was dug out with adapter and had leftovers of brass cup , that surrounded bottom of the fuze and surrounded the tube.
WIch means its a classical field howitzer schrapnel 16 ..

Please enlighten me , Alpini , this one s for You.

Interesting find! Aren't there any markings visible?

In my opinion it's a H.Z.05 (17) Schr. which was made from an altered H.Z.05 Gr. body. Compare it with a H.Z.05 Gr.

But in this configuration it cannot have a percussion function. I am not sure if there was a H.Z.05 Schr. Flak without percussion system.

Il make pictures later.
The markings that could be seen , are "hz 05 schr Sb 16"
Il take a look under proper equipement. Maybe theres a 17 " marking leftovers , need a proper light.
Also il do the comparation with the 05 gr.

Could you tell a little about flak version , heard about it once but never seen it.

 

[Alpini]

No, sorry. I don't have information if there was a H.Z.05 Schr. Flak. But the H.Z.05 Gr. Existed as Flak type without percussion function.

So heres the hz 05 gr for comparison , it looks more like the old original one.

Btw the adapter (head peace Of the shell had steel shrapnel fixated in sulfur . And the central tube was also steel , i belive sulfur is a standart compound for german shrapnels?
Why sulphur , when exposed to the fire it gave yellow - greenish fumes quiet dense.

 

[Alpini]

Just a guess but they may have used Sulfur because it was available cheap from all the gasworks and coal industry. And it was possible to melt it with relatively low temperature and it is solid at the needed temperature range. The oldest German shrapnel shells from the 1860's used Sulfur too maybe also the much earlier British shrapnel's?

Its a fair point , il get to it in books , but current question is , how does the topics hz 05 schr provide heat to the central tube if theres no holes in the bottom .

 

[Alpini]

Have a look at the small holes or the groove below the fuze thread. But thats for time delay only.

So it appears that this hz 05 was for time delay only , btw the ring with the holes was so deformed that i had to scrape it out.
Alr , thats something , il take a look what Bernand delsert writes about this , il message him persobally , we need the truth.

Do you have early pattern Hz 05 schr fuze scheme ? I dont understand what are the bottom screws for .
Books feature Hz 05/17 , but not the common one.
