For sale is a lot of 6 vintage radio crystals, various sizes and types.  They were found in the "collection" of vintage radio artifacts, left behind by my late father.  He was a U.S. Army Signal Corps Radio School instructor during WWII, and was an active and avid HAM radio operator for over 70 years!   After the War, he ran his own radio and other electronics service business.  He LOVED radio!!

I have no knowledge of how to test these pieces, but I know my dad would want some other collector to have a chance to see or own these items.  I hope that one or more of these crystals would be a nice addition to YOUR collection!
