Can any of you identify these battle packs"

[Chickenthief]

They are indeed 7,92x57 Mauser M08

Trageslaufe = Carry handle

Made in the 9'th month of 1940

Patrone s S = Schwere Spitzgeschoss = Heavy bullet (197,5grains)

Code P 635 = Gustloff-Werke, Otto Eberhardt-Patronenfabrik, Hirtenberg Niederdonau

Then it says a lot about powder used and load (and who made it), primer used (and who made it)
