A very rare piece of original WWII German insignia here. This shoulder board was worn by an LSW (Air Raid Warning Service) Warnzentralefuhrer or SHD (Security and Assistance Service) Bereitschaftfuhrer, specifically one who was also a veterinarian. The rank implied here is the 3rd highest rank within these organizations, and the cipher makes this already rare board hyper specific and unique. Unfortunately, it does show some mothing which is visible in photos. Still, not something you will likely find again.
