Hi Volkbert -
I'll get those "maschenengewehr" shots up and running for you all probably tomorrow. Monday by the latest, I promise. Then, I'll email them over to you to put here on the thread. ( Thank you in advance ).
Concerning your Demjansk, is it a first pattern steel stamped piece, or a later zinc award? My own is a Luft. backed zinc award. Any markings on the award on back? Four pin, or two. Blunt ends or slanted? What sort of backing material? The reason I ask so many questions concerning it, is due to this being one of the most reproduced arm shields, and is, in my opinion any way, the best reproduced one of the five major awards. I can usually locate the fine differences between an original and a reproduced piece on the other four, but the Demjansk gives me problems at times. I have only ever owned two of these that I deem to be good, both zinc type awards.
Sam Goody, a member here who doesn't post much ( c'mon Sam, let's get moving here! :>

, make a post ), located a first style stamped steel piece on Jamie Cross's sight that looks good, although I haven't seen the piece yet in person. Tough award to determine, the Demjansk at times.
Be good to each other.
