These goggles have a black base coat with an antiqued silver finish and pewter finished extension rings on each eye cup. Painted and finished with a flat protective clear coat. Each extension ring is secured by three brass knurled nuts and a set of three silver gears. Pewter gears are in each eye piece as well and gears are mounted to each side with brass acorn nuts and silver hexagonal stand-offs. They include 2- 50mm clear lenses, 2-50mm shade 3 green lenses, and an elastic head strap. The lenses can be removed and exchanged or replaced. One of a kind. Thanks for viewing.
