Vintage American Optical Ful-Vue Pince-Nez 1/10 12K GF Glasses US Army Case Pati

Step back in time with this authentic vintage American Optical Ful-Vue pince-nez eyeglasses set, circa early 20th century (likely WWI/WWII era). The rimless frames are marked "AO 1/10-12K GF" (1/10th 12 karat gold filled) and "Ful-Vue," a patented design known for its secure nose grip and flexible cable temples. Clear glass lenses are intact, with diamond-pattern nose pads for comfort—perfect for collectors of antique eyewear. Includes the original leather case embossed with a United States Army seal, tying it to military history (AO supplied optics to the US forces). Shows age-appropriate patina and wear, but structurally sound; non-functional for modern use without adjustment. A rare find for militaria or optical enthusiasts.
