A vintage unmarked inductor/transformer had been lying neglected in my junkbox for decades and I had to resurrect it.
Resistance checks showed that 2 windings, with a tap each, are terminated in its 6 pins. One measured 70 Ω with a 5 Ω tap and the other less than 1 Ω. A threaded core, with a movement of 5 mm is situated at the top of the unit.
