WWII FT243 Crystal Manufacturers
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. TIA - Joe (G3LLV) |
