Crystal Tuner Genuine 4096Hz Frequency Sound Wave Purification 

Welcome to my auction for this vintage estate fresh find!  This is a crystal tuner tuned to 4096Hz or cycles per second (cps). It measures just over 3.5" in length and is just under 1" across. There is some discoloration from previous uses, shown in the photos. The tuner comes in a blue velvet bag and papers explaining the crystal tuner and how to use it, as well as some history.  

Thank you for looking and happy eBaying!
