U.S. Military Lensatic Compass
About the size of a U.S. Dollar Bill when opened, this compass is Olive Drab Green. It has red numbers representing degrees and black numbers representing mils. The tritium in the compass is in all parts required for navigation (bezel, north seeking arrow, "E," "W," and the pointing end. It has a 1:50,000 scale on the left edge measuring up to 6,000 meters. There is a wire and aiming sight for precise azimuths. This unit requires "controlled disposal" due to the radioactive tritium. It is identified with a National Stock Number (NSN) as 6605-01-196-6971. This product is available commerically with some effort. If it does not have the "controlled disposal" warning on the back, it does NOT have the tritium, and is probably pre-Vietnam era, and not an "official" military compass, by today's standards. Cammenga has replaced Stocker and Yale as the primary contractor making these. This was updated on 6 October 2013.
