Panzer ID Cards from Waffen-SS Arms Academy

[darksidesw]

Hello all!
I'm looking for some comments and opinions on this set.
I bought these at a recent estate auction. I have been collecting helmets for decades and had never seen these before in my travels. It wasn't until I got home that I noticed that they were all marked to a Waffen-SS Armament Academy and also stamped to the same.
I will likely sell these since I don't collect paperwork, so I am looking for some guidance on them. Anyone else seen these that are SS marked?
Any help would be appreciated!
Thank you-Jeff

Hmm interesting the Ram and the US M6 both tanks that where never used in battle.

I guess propaganda around them was successful.
