I've been watching this thing for a couple months at a flea market and got the vendor to come down on the price today. It's a 1965 Civil Defense CDV-700 radiological survey meter, or Geiger counter. It detects beta or gamma radiation sources like radium-dial wristwatches, uranium glass, etc. There used to be hundreds of thousands of these all over the U.S., in every fallout shelter. I ended up giving $40 for it and they typically sell for $100 on Ebay. Probably just keep it for shits and grins.

Apparently it works great for being 53 years old and the calibration seems to be fairly accurate. It take four D-cell flashlight batteries and has an operational check source on the side, which is probably depleted uranium. The source measures 2 mr/hr with the switch in the X10 position. I have a Vietnam War era U.S. Navy NC-1 waterproof compass with a radium dial. It measures a whopping 10 mr/hr.

I also found (not pictured) a lot of Civil War era Sharps carbine parts, including one complete lock, one complete breech block with lever, five lock plates, and a shitload of other parts for $20. The last lot I found brought $850, we'll see what I can get for this one.

Find anything radioactive? I'm going to go through my huge pile of junk and see what I can find.

Kinda wish I had this when I got dinged for shipping that Korean War US Army compass to the UK. It set off the radiation detector at the UK Customs, and I got a nasty letter from the US Postal Inspector, carbon-copied to the DHS.

Oh yeah, I used to use it when I was out looking for carnotite
