This is a set that I've been hanging on to for years since I had these available, but I simply don't have a use for them. These did work with a 9V battery (and a homemade adapter that I have since lost but can me made for $10 at a local hardware store) and an infrared flashlight, but I haven't tested them since. Complete kit as would have been issued to vehicle crews. Dated 1967. VERY rare and hard to find Gen "0" night vision.
