These vintage 1940's glasses are in very good shape for their age. One of the nose pads is a little wiggly. And there are no cracks on the glass at all on either lens. They do have bifocals built into the bottom of them They are prescription glasses in working condition. On the side of the ear pieces if you have a very good magnifying glass, it reads AO 1/10 12 KGF And on the nose piece, the Inside of bridge between the lenses it is stamped Squire  AO If you have any other questions, please feel free to ask. Thank you very much.
