Wm B Johnson GSM-115 Geiger conter survey meter works - $320 - (St. John, KS)

Purchased this about a year ago and it was new. Detects Alpha, Beta and Gamma emissions. Used very little, checked some pottery and plates to see if they were radioactive. Has new batteries in it. Probably needs calibration for serious use (a year or so old). I just don't use it anymore (75 years old and counting!) Will ship in USPS ground well packed. Any questions please ask. Looks like new and was gently used.
