These goggles have a blue base coat with an antiqued silver finish. Pewter extension rings are mounted to the front with an extra set of nickel finished extension rings that are extended by three hexagonal stand-offs and secured by three black oxide nuts on each eye cup. Painted and finished with a flat protective clear coat. A spike is also embedded in each extension rind and held in place by a silver knurled head screw. Gears and brass knurled nuts are also mounted to each side. 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.
