I have a brass plate between the knocker and the bell that says

I'm still pondering adding a circuit to the knocker so that, if used, a
loud voice intones: "PLEASE USE THE BELL!!".

Trigger a jacobs ladder from the knocker, or maybe just remove it?

Many people were strongly in favour of the Sun's Page Three models
but they also had their knockers :-)
