From what I see so far I do NOT like it .There are now a lot of fake / reproduction Fahna rings out there now.
The best way to know , of course is to have a real example in your hands for study. Once you have a real one in your hands
it is early to spot a reproduction. I am lucky to own several original Imperial German regt./ Batl unit rings.
Two that I own are still on the original fahna poles with flags. Several of the ones that I have came from the Jan K. Kube
special sale back in 1999.Once I was offer a repo ring for a unit of which I already owed the real one.
As far as the U R 8 ring; First I would do the following ;
1.see if the U R 8 flag is in the DHM
2. check to see if the U R 8 flag was taken to Russia after WWII
Here is an example of real I R 72 / F B ring on the right
the copy ( while well done ) is on the left
they just didn't get it right
