10k SOLID GOLD AS MARKED AND TESTED. Antique American Optical Co. spectacles from the late 1800's. Wire rim glasses marked "A O CO" and also has the 10k gold mark of a circle with a line through it or pill shape. The case is wrapped metal. The case states "HT WITTLIG Optometrist 208 Front St. Marietta O" Along with these having the gold mark I also tested them as seen in 5th picture. They are 4 1/4" across the front. The bridge is approximately 3/4". They are 4 1/4" long but of course the backs can stretch a little. Condition: The glasses are wearable with no chips or scratches on glass! The case has wear as seen in pictures. The glasses themselves, with lenses, weigh 10g. Let me know if you have questions....thanks Location E1
