Cartridge case (kind of…??) or WHAT… ?!?
Tis is a Russian designed, electric primed “PP-9” (or one out of this series) CAD.
Made by several countries and used in many applications.
Some are holding a propelling charge or special ignition compositions and some are just the electric primer with empty body.
Often used in aircraft and also as igniter for rocket motors.
So…nothing about WW2…;-( (strange somehow: I found a few like this one…almost in the same place…!?!)
I do not have a WW2 doc covering it but these were also used in M13 (132mm) MLRS “Katyusha” rockets.
So this could be also WW2 to my understanding.
Interesting information !
I don’t have any other explanation for so many “electric cartridges” (like this one…) almost in the same place…maybe a “Katyusha” have fired from that place (or from nearby…) .
But… could only soviets used this type of cartridge… ?
When fired these are installed in the rockets, means they fly away.
But as said these are used in a multitude of applications. So could be many other options here.
Soviets or anybody who used Soviet armament.
