The previous owner was a Ham Radio operator who collected all of these interesting items over the years. He really focused on purchasing equipment from special surplus auctions at the Nevada Test Site, Sandia Labs, Nellis Air Force Base, Kirtland Air force Base, etc. Many of the items we have are from EG&G, Department of Energy, NASA, Air Force, Navy, Marines and Army. The previous owner kept notes on nearly everything as it seemed to be his life-long hobby to collect, test, and document everything he owned.Manufacturing technology was not the same as it is today so imperfections should be expected. Also, these items may have been in storage for 40-80 years and could be dusty, greasy or have surface rust, spider webs, etc.
