General Radio 1422-CB 1100pF Variable Capacitor (1963 $300.00)

These are capacitors made in the 1960s and fit well on a physical scale.

In SLC-5020A, the actual capacity between terminals is measured and displayed.

In the impedance bridge method, a stray capacitance of 39 pF (capacitance between shields) is subtracted from the measurement.
