Original Heer Beamte auf Kriegsdauer/Sonderführer collar tabs?

[bittaker]

Here is a pair I am thinking of bidding on?! They look worn, but that is fine by me. I believe they are original and be of "elevated career and medium career with officer rank" after looking at this thread: Need help - Collar Tabs
But I would appreciate if someone had the time to give me a second or third opinion on originality!
