A three lead voltage surge protector used for protecting telephone and other circuits from very high voltage surges. Gas filled discharge allows high current spikes to be handled.

A ceramic capacitor with two ferrite beads. Centre lead is one side of the capacitor and goes to ground.
The line to be suppressed connects to one outer lead and passes to the other via two ferrite beads. The other side of the capacitor is connected to between the two beads shunting interference to ground. 270pF 100V rating.

Vintage tuning capacitors, 1/4 inch spindle, ceramic insulator, silver plated all over (a bit tarnished, but OK)
