Description
A pair of vintage square-frame aviator sunglasses featuring gold-filled wire construction. The design utilizes a double bridge and thin temple arms, common in military-spec and civilian pilot eyewear of the late 20th century. The lenses are a classic dark green, though currently showing significant damage.
Key Features
Double-bridge aviator design, square lens orbital, gold-filled metallurgy intended for durability and corrosion resistance.
Color & Finish
Dull gold/brass tone with heavy surface oxidation, pitting, and gray-green patina. Original finish was likely high-polish gold.
Hallmarks & Stamps
No hallmarks are immediately visible in the provided image; typically located on the inner bridge or temple arms (e.g., "1/20 12K GF").
Dimensions Estimate
Standard adult size; approximately 140mm temple length, 55mm lens width.
Gemstones & Inlays
None; features green-tinted mineral glass lenses and acetate/plastic temple tips.
Clasp & Closure
Standard barrel hinges with screw-pin assembly.
Chain & Links
N/A; flat-profile wire frames with soldered bridge and nose-pad arms.
Craftsmanship Details
Machine-pressed frames with soldered components; the precision of the solder joints suggests mid-tier mass production.
Authentication Indicators
The heavy pitting and greenish corrosion on the metal surface suggest a gold-filled or plated construction rather than solid gold, which would not oxidise in this manner.
Origin & Maker
Likely American or Italian; style is reminiscent of Bausch & Lomb (Ray-Ban) or American Optical (AO).
Era & Period
Mid-Century Modern to late 20th Century (circa 1960s-1980s).
Age Estimate
Circa 1970-1985 based on the square aviator silhouette and the degradation of the acetate ear socks.
Cultural Significance
The square aviator style became iconic due to its adoption by US military pilots and later popularized by Hollywood cinema and fashion icons.
Condition Notes
Poor; lenses are cracked/shattered, metal shows heavy pitting and oxidation, temple tips are yellowed and brittle. Structural integrity is compromised.
Value Estimate
$20 - $40 USD. The value is negligible due to the shattered lenses and severe metal degradation; the gold melt value is near zero given the 'filled' nature.
Care & Maintenance
Requires professional restoration. To clean, use mild soap and water; avoid ultrasonic cleaners if lenses are cracked. Metal requires specialized jewelry polishing to remove oxidation.

Interesting Facts
Gold-filled eyewear was the industry standard for high-quality frames before the 1980s because it provided the look of gold with much higher tensile strength for thin wire frames.
