Hi Trevor,
I don't know of any commercially made battery TRF radio receiver that has an anode bend detector.
In practise it's easy to implement, just use a separate 1.5 volt cell for the detector valve filament.
No high slope battery RF pentodes were ever made. The 1L4/DF92 has a slope of 1.03mA/V.
