I believe NCO's could Private Purchase officer quality items .
Reminds me of that well known saying
"Don't tell me they would have worn that!!"
Looks like officers collar tabs - breast eagle/tunic too, for walking out I would think......... one proud soldier!
Lovely picture BTW
When you're wounded and left of Afghanistan's plains,
An' the women come out to cut up what remains,
Jest roll to your rifle an' blow out your brains,
An' go to your Gawd like a soldier." - Rudyard Kipling

He's a Beamter [official] of the Feldpost [field postal service].
Rank is equivalent to a Feldwebel; he is a Feldpostbetriebsassistent, Feldpostoberschaffner or Feldpostschaffner.
His insignia are of the type worn by officials. The Waffenfarbe [branch color] for army officials was dark green and is seen as the cap's piping and the base underlay of the shoulder boards.
The Nebenfarbe [secondary branch color] for the Feldpost was lemon yellow and appears as the three-sided piping of the collar patches and the secondary underlay of the shoulder boards. The center cord of the shoulder boards is also in the branch color, which was unique to the Feldpost.
