Authentic WW2 German Badge, Gespensterbrigade Angern, Ghost Brigade 11th Panzer

Description

Ready to part with this family heirloom...a 1940s/WWII era metal uniform pin inscribed Gespensterbrigade Angern S. R. 111.
Please scroll down to read my response to someone accusing me of selling a reproduction.
This vintage military pin features a skeleton head ghost with an eagle claw for one hand, holding a knife in the other, with a sash around the waist and it's feet on a tank. This piece measures 1 inch in diameter. There was some red wax/crayon embedded in the nooks and crannies. I did my best to wipe it out with gauze, but some remains.
I will leave the final cleaning to the new owner.
Gespensterbrigade translates to Ghost Brigade, so named by it's second commander, Günther Angern.  S.R. stands for Schützen-Regiment which translates to Shooter Regiment.
From Wikipedia:
The 11th Panzer Division (11th Tank Division) was an armoured division in the German Army during World War II, established in 1940. The division saw action on the Eastern and Western Fronts during the Second World War. The 11th Panzer Division did not participate in the war until the invasion of Yugoslavia. It fought in the Soviet Union from 1941 to 1944 and, in the last year of the war, in southern France and Germany. The formation's emblem was a ghost.

"This is an obvious repo, because German did not make badges so poorly made as the backside shows, especially having no maker mark either!"
Response (outside links to research articles are available upon request):
Thank you for your comment, however, I can assure you this is a family heirloom and authentic.
If I didn't know where this came from, I could check authenticity as explained in post #10 of this thread:
As mentioned in the thread, my numbers and letters have stripes inside them (see my close up photo).
Additionally, not all had maker's marks, and not all fasteners were the same, either. Many had to have a new pin attached (some more professionally than others)!
I've been selling on eBay for 20 years. There's no way I would risk my reputation by selling a fake.
