7,9 Pz B Patr 35 [p] problem with labels / propellant

Hello,

I have a problem with info. about propellant on the paper labels for 7,92 x 107 cartr. from Velten.

Label in left / right:
Nz.R.P. / Np.R.P. [!!]

and no significant difference:
S.K.D. 39. L.40 - S.K.D. 39 / L.40

Rest info the same… In Nz/Np - maybe only mistake in printing label?

Regards,
PM

Yes, in my opinion “Np.” on the right hand label is a typo and should be “Nz.” The German Patrone 318 also used a very similar nitrocellulose tubular propellant (2.8x2.8/0.5). Development of a new Np propellant for the limited supply of Maroszek antitank rifles seems very unlikely.

P.S. Moschwig was one of the Np propellant producers, which may explain the typo.

Thank you for the opinion!
Yes, it was strange for me that. I always met boxes for “patrone 318” with Nz.R.P. on label.

Not to ruin the thread with other questions but is anybody able to clarify on the exact projectile that was used here?
As it has a TC core and no “Rs” (irritant) it must have been a different projectile than was used in the Patrone 318!

So far i knkow only 2 German TC designs. The one for the Patrone 318 and then the SmKH. Both (supposedly) not being the one mentioned on the label(s) above.

from not published yet articles:

ŁADUNEK MIOTAJĄCY
Nie wiadomo czy w początkowym okresie wykorzystywano jeszcze zapasy prochu polskiej produkcji. Jednakże po przeniesieniu produkcji do Niemiec zmieniono go na typ oznaczony symbolem:
Nz.R.P. 3x3/0,5.
Był to proch nitrocelulozowy w kształcie rurek o wymiarach ziarna 3x3mm i otworze 0,5mm. Proch pochodził z zakładów Deutsche Sprengchemie z Moschwig (wg danych zachowanych na etykiecie opakowania). Wielkość ładunku miotającego wynosiła 10,4 [g].
Co ciekawe był to inny typ prochu niż stosowany w amunicji Patrone 318, gdzie używano prochu typu:
Nz.R.P. 2,8x2,6/0,5 (z pociskiem Geschoss 318) przy elaboracji ładunkiem 15 [g]

PROPELLANT
It is not known whether Polish gunpowder stocks were used in the initial period. However, after moving production to Germany, it was changed to the type marked with:
Nz.R.P. 3x3 / 0.5.
It was a nitrocellulose powder in the shape of tubes with a grain size of 3x3mm and a 0.5mm hole. The propellant came from the Deutsche Sprengchemie plant in Moschwig (according to the data on the packaging label). The propellant charge was 10.4 [g].

Interestingly, it was a different type of gunpowder than that used in Patrone 318 ammunition, where gunpowder was used:Nz.R.P. 2.8x2.6 / 0.5 (with Geschoss 318 bullet) for elaboration with load 15 [g]
