Well, yes and no. Until 1935 and the removal of the
Oberbann as a structure, not all Gebiete had an Oberbann 5 or 6 because they simply weren't large enough to require that many. However, within all 5 Obergebiete at that time (Nord, Ost, West, Süd and Mitte)
all of the Gebiete had an Oberbann 1, 2 and 3. This means that members of
any Jungbann within Oberbann 3 of
any Gebiet up to 1935 (removal of the Oberbann as a structure) would wear the green rune patch.
For example:
In 1934, Jungbann 1/61 Neukölln was part of Oberbann 3 Berlin-Süd within Gebiet 3 Berlin so its members wore a green Oberbann 3 rune.
However, 670 kilometres away, Jungbann 1/245 Mittelwald was part of Oberbann 3 Birkenfeld within Gebiet 12 Westmark so its members also wore the green rune patch.
