This is an old manufacturer manual on the inspection, maintenance, and use of the CDV 457 Model 2 radiation survey meter.  This is a old meter from the cold war, but its still around on ebay and other places.

I keep it as a reminder of my days in radiological training at TEMA, but in all reality, there are better devices on the market today and it is getting hard to find someone who can calibrate and maintain these old devices.  A device like this needs to be maintained by a shop with the right equipment and most of those were old government facilities that are shut down.
