Hi! I just bought a ring with the name Muller
on the outside band.
I just can't find any picture of it on this
forum. Can someone explain to me where this
ring is about? Thanks!

welcome to the forum le marin...
If its a skull ring with snakes or serpants and it has 800 and Muller stamped on the back,,,if its the one I'm thinking of its not a German military or organizational ring...
