Don't forget PR. The recent QST has a short on them being still in
business..
I'll have to go check my pile...

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)
