Hi,
It's indeed a SA-Wehrmann tunic, but the mod. for EM/NCO, the officer one is a little bit different.
Here with a pic of the regular headwear wich goes with the tunic, the so called "SA-Wehrmann M�tze".
You could also use a SA-Wehmann M43, it's easier to find.
But the uniform could be worn in this configuration, "Volkssturm", war end fighter...
