Waffen SS collar tabs for SS- Ostuf or SS-Ostubaf

Mint condition Waffen SS Obersturmführer or Obersturmbannführer. Never used. Absolutely matching pair, which is hard to find, made at the same factory.  It's a mid war collar tabs made on moleskin cotton badge cloth. The tab missed the RFSS paper tag with C letter only, or most probably it never had it, as most of other SS tabs seen without any labels. Absolutely nice tight aluminum thread embroidered runes. Aluminum cord and rank Tresse has been applied by a tailor and the tabs are ready to be sewn on the tunic, but by some reason they were forgotten for 70+ years.  It's a fact, regulated by order that the aluminum cord piping and rank insignia been never added by factory, and that was a duty of the soldier wife, himself or tailor to do this work.
