hi mike
if it reads sterling and 10kt this is my opinion the ring itself as i mentioned untill you said now that it is marked sterling silver and 10kt this is what i think happned the ring itself was sterling and maybe there was another insignia mounted on the ring before then the airbore u.s. soldier decided to take off the insignia that was marked 14kt gold actuly it probly was like our u.s.navy officers cap eagles that were marked sterling and 10kt dipped on brass but now its not a german blank ring its u.s. still a great airbore ring thanks for showing it to us here on this great ring forum have a great day andy militarynut
