458U246 Mallory Inducto Tuners, no actual data, but I put
a coil loop and 100pf capacitor across the coil
and used a dip meter to determing the resonant
frequency. All dipped in approx the 40 - 60 mhz
range. Mallory made most of these for early VHF
television sets that had variable tuning, no
7.5 turns, 41-67 mhz, 7.1 x 2.25 x 2.1, 2.4"
long x 0.25" dia shaft. (T1V) Unused Sh Wt 3 lbs,
