Ww2 M43 82nd Airborne jacket help

[Von Stahlwerk]

Hello guys

I have a question of authentication and there are some weird things on this jacket I don't understand.
It has a sewed on 82nd patch on the left side, I guess it's post war added. I'm not sure.
Then on the right side, in fact the wrong side, there are stitching marks that have the same diameter and chape of an 82nd patch and on the inside, there is a piece of yarn that is not glowing under uv light.
Here some pictures.
