Well, ostensibly this is an early pennant dedicated to Ernst Röhm but the details don't compute.
That Bann eagle design was used on the standardised HJ Bann-level flag but these were not introduced until 1935 at which time Röhm was long dead and disgraced in the eyes of the NSDAP.
The scroll says "Berlin" but the design is mimicking a Bann flag where of course the scroll would contain the Bann number.
"
Bann-1". Bann 1 was Königsberg after the July 1933 reorganisation. Prior to that, the number one had been in use in Niedersachsen as an Unterbann number (many Unterbanne were upgraded to Bann around this time) until May 1933 when it was replaced by 92. Basically, Bann 1 has nothing to do with Berlin. The lowest Bann number there was 6.
"HJ-VIII" "Bann-1": Strange to see things hyphenated like this but if we forget the "HJ-" part, HJ Gefolgschaften were numbered that way after a 1932 reorganisation completed in April 1932 but the word Bann had not yet come into use so "HJ-VIII" and "Bann-1" together on a Wimpel makes no sense. If we assume that "HJ-VIII" means Unterbann VIII then that too is a big, big stretch because only the very largest Gebiete like Westfalen would have approached numbers that high. It's possible though that these numbers could be designating an Unterbann but then again, why is Röhm's name on the pennant at this stage?
I suppose the point could be made that this was stitched by a kid who wasn't fully up on current affairs and who didn't know how to correctly designate units but I can't see it. This is not a pennant I would go for.
