German panzerfaust tube

Here a strange item I never saw before.
It is a black pressed carton tube that was used to storage panzerfaust ( anti-tank weapon).
Probably a transport crate.
It has the text “1 panzerfaust treibladung GM42 2 treibladungzünder DM47”
Attached are some webbing straps that have an unknown use to me.

After my last update I got an email from a friend that guaranteed me that the tube is for sure post-war.
Probably even from the 70’s !
