Not sure where to place this
but I will start here
Sad to say this is not my helmet
but in the collection of a friend
I had never seen a Kammer issue stamp
on the back of a leather strap
So I took this photo.
Has anyone out there ever seen one like this before ?

I saw such a marked chinstrap on a bay 7 JR helmet. The helmet and Uberzug were too marked with 7 JR marking and the helmet was genuine, the chinstrap has been on this helmet since the beginning.
