I have an old Bliley LF crystal, frequency= 118.05 Kc, with ser. No. and it is type BH8. Appears to have been manufactured in Aug. 1953. Anyone have any idea where it may have been used? My guess is an LF beacon. It on has two pins and is in a round can dimensions: 2-3/16" high x 1-7/16" dia. Ralph, VE3BBM
