Vintage Airco Noviweld Welding Goggles with original box, 50mm lenses, adjustable ball chain bridge, and multiple spare lenses (including marked NW/AG shades). These are classic mid-20th century American-made welding goggles from Air Reduction Company (Airco), designed for oxy-acetylene welding and cutting. Features include snug-fitting individual eyecups for maximum eye protection, indirect ventilation to prevent fogging/sparks/light penetration, greater vision field with shallow 50mm lenses, and comfortable fit per U.S. Bureau of Standards and Navy specs.

The set includes the original yellow box (with detailed instructions and ads for Noviweld lenses), the black rubber goggles with strap (some age wear/cracking but intact), and a bunch of extra 50mm lenses (dark shades for heavy/medium welding, plus clear covers?). Lenses marked like NWAG6, showing Noviweld branding for UV/IR protection.

Great for collectors of industrial/vintage tools, steampunk decor, welding history, or man cave displays. Condition: Vintage used—box torn/aged, goggles show patina/rust/wear from storage/use, lenses have some scratches/dust but functional. No major damage; strap elastic may need care. Sold as-is, uncleaned for authentic patina.
