Thank you for your help! I am always afraid of my mirrors. Finding out it was a hole reinforcer was a big help. Also finding I could use other solvents than water was a big help.

I soaked it in distilled water with no results. Then I soaked it in solvent grade alcohol still with no results. Then I soaked it in lacquer thinner and found it softened slightly. I noticed there seemed to be a clear film on top of the circle. (This is the scary part! I have been a string intrument maker professionally for 14 years and have acquired a great deal of hand skills.) I took a brand new razor blade and carefully parted off the clear circle. I was very careful not to touch the mirror with either edge of the razor blade or my hands. Once the plastic cover was off the lacquer thinner turned the rest into jelly in a matter of a few seconds. I was able to pick off the remains with a q-tip. I then washed the mirror in lots of distilled water and blew it dry with dried air.

End result A-. I can still tell a little where the ring was but it does not show in my image.

Thank you again.
