VERY OLD.  MOST LIKELY FROM THE 1800's.  

14k SOLID GOLD pads.  ETCHED THROUGHOUT!  I am assuming the rest of the glasses are gold filled.

The pads and bridge are marked as seen in pictues.

They are 4 5/8" across the front.  The bridge is approximately 5/8".  They are 4 1/8" long.

Condition:  The glasses are wearable.  No bends in the metal.  Still flexible.  No chips or cracks in the lenses.  Maybe a few small scuffs at most.

Let me know if you have questions....thanks
