a lot of these were made in the late 60s and 70s from original Zeltban,from a large stock found in Austria.
The material appears to be HBT, not zeltbahn material... Strange...
Not feeling the textiles on this one. Would need more close up pics, especially collar and sleeves (under arm). But not for me from those pics
Be careful, there is a seller in France on ebay ( big surprise right!) who sells fake german uniforms as original. This looks like his type of item and photographs.
Fake HBT material - weave of the HBT is far to big - Looks like a Janke to me.
Material and reverse button holes suggest to me to stay very far.
