Vintage WWII US Navy Fighter Illuminated Gun Sight Mark 8 MOD 6 Working. Excellent condition, working reticle. FOR GUNSIGHT COLLECTORS: US Navy Bureau of Ordinances Illuminated Sight Mark 8 Mod 6. History: According to aircraftgunsights. Com, In 1941, the US Navy adopted the British GM2 Gunsight (designated the Fixed Gun Reflector Sight Mk II) as the basis of their new standard Gunsight (designated the Mark 8 Illuminated Sight) for fighter and attack planes equipped with fixed forward-firing guns. License agreements for the production in the US were initially signed with Bell & Howell and Bausch & Lomb (later expanded to the companies Kollmorgen Optical and American Cystoscope) and from early 1942 onwards, the MK 8 was gradually fitted to every fighter and attack plane in the Navy inventory: F6F Hellcat, F4F Wildcat, TBF Avenger, FU-4 Corsair, and P47 Thunderbolt. All MK 8’s could be either used with or without a fixed reflector glass (in which case the reticle was projected directly on the armored glass windscreen or to a reflector glass fixed directly on the windscreen) or with an Adjustable Reflector head for rocket firing and/or toss bombing. The last two photos, which illustrate the Mark 8 installation and function, were added for historical reference. This Gunsight includes the light elbow with fully tested and functioning Mazda GE 28VDC light source. The inside of the bulb is mostly mirrored so the light shines out only at one spot. An original bulb (rare) for the MK-8 was recently found as new old stock and is now installed in the sight and working. See illuminated reticle photos.
