WWII FT243 Crystal Manufacturers
Joe McElvenney wrote:
Hi, Yesterday I bought a 'BOX BX-49-A' (coil/crystal set for the BC-611 walkie-talkie) with a view to starting a crystal collection. It contained 24 FT243 rocks from eight different WWII manufacturers. Just to get an idea of the task ahead, has anyone compiled a list of these manufacturers from that period? The few I have so far are marked - Univ K.C. Telev M.O. Valpey Crystal Turner Company, Cedar Rapids Scientific Radio Prod. RS MC Camb Thermionic, Camb Mass Gentleman Products, Omaha H.I. Inc Stand. Piezo M.P. CO. Joe, you may add Tedford Crystals (later R/T Labs), Cincinnati, Ohio. Dave Heil K8MN |

Joe, you may add Tedford Crystals (later R/T Labs), Cincinnati, Ohio. There was even a crystal manufacturer in Griffin, Georgia! I'd hate to think how many there must have been at one time. |
