Isnt it an eagle on the left shoulder of the ustuf in the grey uniform?
Nice info FB, looks like the same type of uniform as the ustuf, in the photo.
I've always thought that Ritter Von Hengl was a Gebirgsjäger, but a quick search shows that he joined Standarte Deutschland from october 1934 to october 1935.
A well-known photo, but a truly fine study of the earliest uniforms worn by the armed SS formations.
This was still prior to the introduction of grey peaked caps, army-style shoulder boards, SSVT-pattern sleeve eagles and the SS honor sword.
Also of note is Hengl's Militär-Max-Josephs-Orden, with whose bestowal came his "Ritter von" title.
I also note that one of the SS personnel is wearing what appears to be a Braunschweig Treffen 1931(left side yellow square). I cannot quite make out the award on the other chaps uniform(right yellow square). Leon.
