Can anyone identify this maker mark?

[Robert P.]

Does anyone have any idea which maker stamped this ring? Am I seeing a '12' in there?

To my old eyes the stamping looks like a 56?

Stefan,

You're exactly right. I looked at my 132, which I never gave a thought to until you posted this, and it's exactly. Good eyes and brain.

Thanks,

as always - a pleasure for me
