He wears a brown tie, so he is possibly SA, maybe he is Motor-SA as he does wear an insignia beneath the armband.
Amyway it looks if there is an insignia.
His breeches seem to be a darker-brown and not black (compare with the black from the person next to him) and black
should be worn within the Motor-SA anyway since 1933.
He could be NSKK for the reason the NSKK did wear a brown tie until later 1935. His breeches should be black instead
of brown or darker-brown. This was a general rule since 1934. I did check SA as well as NSKK regulations and Motor-SA.
If we would have a better photograph and know about the shade for the breeches, then we would possibly know for sure!

I have had another look at the picture to see if I can help with the debate on uniform but the original is very blurred, due to the subjects moving I reckon, so a better resolution will not assist I'm afraid.
There is another group shot of the same soldiers which is slightly better quality and I will scan it tonight and post.
Looking under the magnifer didn't help either as the insignia is not that clear, NSKK is likely because of the uniform and the fact
that the RW unit are shown on motorbikes on the next page, maybe they are on manouvers together ?
Having re-scanned the pictures I am quietly confident that these new images will be no help what so ever !
Sorry the original are too blurred to scan at any high resolution that will assist.
The guy in the middle has the brown shirt and three pips on his left collar tab alongside a round officers belt......any help ?
