for instance.

Being lazy, I searched for "another single pot tunable band pass network called Hall’s network"

Thank you:Do you have a reference to it? Google doesn't help, because the name has been re-used. The Pease circuit will tune over a decade with 100:1 change in R2 value, which is just about practicable, 100 ohms/100k.

it can tune over a decade. The commercial worked example is used in the general radio model 1232a tuned amplifier/null detector. It is a different circuit than Pease’s.
