Hi! I have a Pair of Antique Gold Tone Metal Wire Frame Eye Glasses with a Hard Case from Buffalo Optical Co Buffalo NY.

The Gold Wire Frame is on the Top Half of the Lenses with Hooked Wire Sides.

The Bottom is rimless.

There are marks on both the bottom of the nose bridge and one of the Side Wires.

The writing is small and hard to read (even with a magnifying glass), but I think they are gold filled.

I tried to show the marks in the photos.

Thanks for looking and have a great day.
