Thank you to all who replied to my request for info on the mfr of these
xtals during the war. I'll reply to each of you individually.
Scott mentioned Galvin being one who made the most. Haven’t come across one
of their's..yet..but my only 'G' entry so far is from " Gentleman Products
Omaha "
Got to wonder about that one...

Thank you
