Looking over some post of similar rings, dug this out for comparison.

Thanks

There is period photo with same ring on spldier, which proof that this pattern exist. But to identify authenticity need to see better photos fromthe inside, markings, side and front photos.

Thanks - sorry not the best picture from hurry up photo school, trying to get better photos.

I'm afraid this photos is not enought. Need to see hi-res and hi-quality photos for better result. From first looks ring has correct shape, but detailes are unreadable.

inside ring has a 9 and looks like very small Luft eagle with undetermined mark and 835 K

Inside - Luft eagle ? does not show well, just to the left of jewelers mark ?

Thanks

With eagles on the band?

a German jewelry site list the markers mark as

G. Kramer
Ribnitz-Damgarten

Apparently still in business
