Controvers discussed pattern.
Some collectors say it is a post war fantasy, but i have seen at last one maybe period pic with such ring in wearing.
Usually the stone is onyx and they exist with all different luft badges.
For sure you can buy this rings on the gi website, well known for fakes.
This one has silver hallmarks and looks gold plated.
A ring i wouldn`t want in my collection.
I noticed the silver mark also , so I guess this has no wear to it at all . Not a good sign .
I wouldn't spend any money on it.
Original! There were those rings! I had the ring and quickly found a new owner.
