Luftwaffe Oberfeldwebel Sleeve Rank Insignia
Introduced in December 1935 for garments that normally would not have any rank insignia such as protective flight suits and coats, work and drill uniforms. The insignia came in a series of white “wings” and bars for the ranks of Unteroffizier through to the rank of Oberst and a series of golden yellow “wings” and bars for the ranks of Generalmajor through to Reichsmarschall. The December 1935 pattern of rank insignia remained in usage through-out the war.
The insignia consists of deep navy blue wool bases with four white wool “wing’s”. Reverse with some old glue, most likely from being removed from a album. Besides that in very good condition.
