Single filament double contact bulbs were the norm certainly well in to 1931. I think the single contact fitting dates from 1932 at the earliest, possibly 1933; brake lights were introduce in October 1933 when the lamp unit was changed to the larger 4" diameter (BG197 in the Parts List), which I think took two separate bulbs rather than a single double filament bulb.
Or buy a reproduction Lucas AT201 from Paul Beck, take out the plastic lens assembly and replace it with the original faceted red glass and plastic side light.
These have a two pin socket and correctly wired provide stop and tail lamp with the appropriate 6 volt 5 / 18 watt bulb.
Cheers, Tony.
