Worlds Largest manufacturer of Radiation Instruments. Also has a tag on it, Reading, Precision Standard of Quality. The tag describes the quality of the product and a pledge of Quality to the public and also a Garantee on back. Tag is very readable but, bent and warn a bit. Instrument in fair condition. Has some pitting on it but, still looks unique. Comes with some sort of headphones and a leather case. On bottom of case it reads genuine leather. (Stamped into Leather). Does not have battery. We don't know too much about this item. Was found in basement that was cleaned out. We have no idea if or how this item works. But is sure one unique item. Great for electronics shop or collector. Instrument is chrome plated and salvagable. Needs some TLC.
