Good afternoon Artur
The Rudge owners club in the Uk reproduce a rear light that looks very similar. Described as 34E

Although a Firefox fan I was still able to view those images by clicking on the vacant space and hitting copy they would down load and I could see them by thaks for coverting them for those struggeling to evade Microsoft

Maby someone have for sale this type resistor or can send some pictures .

Evening Artur
I think what you are showing in your attachment is not the resistor! It looks like the remains of the cut out relay, that's the item that disconnects the battery from the charge source once the battery if fully charged. The cut out is positioned on the frame rear down tube under the seat and behind the battery
The half charge resistor is a wire coil that is an integral part of the headlight switch. I have seen a picture of the rear of the light switch somewhere on the forum just cannot find it at the moment.

And the switch half charge resistor

Not marked and probably not a BTH, but this 1 inch dia rear light of the period.
