via this auction

You can literally see the ladder array in the inside pics below.

From the listing:

"I have only seen this quality of construction on military equipment. I slid the sides off to get the pictures. The four Allan Bradly pots that are geared together for frequency selection give a 24db per octave cutoff slope. This could be the finest analog filter of its kind. Selectable Low Pass or High Pass. Low pass is DC coupled for best fidelity. Frequency range 20Hz to 2 Mhz . COMPLETE bench test. This unit is 100%... Complete specs can be found here."
