VERY OLD.  MOST LIKELY FROM THE EARLY 1900's.  

Made by American Optical.  Marked "Amercian Optical", "1/10 12kgf", "3", and "Artcraft".  SEE PICTURES.

The lenses are Hexagonal shaped and have a slight rose tint.

They are 4 3/8" across the front.  The bridge is approximately 1/2".  They are 4 1/8" long.

Condition:  Still flexible.  Some finish wear on the side backs.  The eye pads are in great shape with no cracks or chips.  Both of the lenses are in great shape with no cracks or chips.
