It is a well known modern fantasy ring. Made in lost wax casting
There are some books about the ss honorring.
I know too a rather large article about Westwall rings.
And my friend Gaspare Bua is working this times on a book about
privat purchase rings of the III. Reich.
I would never buy a ss ring unless I dug it up from the battlefield myself. I saw a video of a man who found one in Latvia. I wouldn't trust any ss rings online.
