Here is a 15-round grenade blanks box for “gross Gewehr Panzergranate”.
This box is similar to that shown page 8-4 in the book “Die Patrone 7,9mm den deutschen Wehrmacht” by Windisch, Micke, Kellner.
However, a few differences which call for questions :
Here the powder is an unusual Nz Stb. P n/A (0,8-0,8), with a loading of 1.9g. What is this powder which seems to replace the usual grenade propelling powder NZ T.P. (1,4-2-0,5/0,25)also keeping the same standard loading charge of 1,9g.
Note that the wood bullet is specified"Schwarz"= black , would there be other colours of wood bullet for the same grenade ?
For the cartridge case, lot number is given 40/44 versch. L : various lots from 1940 to 1944 ? or 40/44 means something else ?
Last but not least this box has been found filled with 15 identical SmE rounds (edq St+ 20 44), this was a vintage stuffer since that box was retrieved by EOD officers in a farm in North-East of France near German border. So which type of grenade blanks was originally in that box ?
Thanks in advance for any comment.
