This listing is for a variety of vintage 1940's / 50's, WW2 / Korean War Era Crystals for Military Radio Sets. They are FT-243 packaged and have frequency in KC and associated Channel number. For the most part these crystals start around Channel 286 and go to 389 typically for Artillery Units assigned by the Signal Corp. There are a variety of Manufactures in this group of crystals and all look to be in great vintage physical condition for being perhaps 80 years old. Electrically, I can not guarantee anything as these are sold untested. Crystals drift with age I understand and so I do not guarantee frequency accuracy either. So if your willing to take a chance on a piece of history then these are for you. I see no signs of physical damage, cracks in the holders or pin damage. In the photos you will notice that the side shots show many of these with date codes from 1943 and 1944. These are sold individually and there is no additional shipping cost if you buy more than one. Buyer pays $4.50 USPS shipping and handling in the US.
