46-48 B31 rear light

Could anyone post some pics of the correct rear light for a 46-48 b31 and how it is fitted.
Many thanks

The Lucas master catalogue 1936-1957 shows the 1945-50 B31 being fitted with tail lamp MT211 part 53056A. You can see the numbers in the first photo. The star means that the part was superceded and a deeper look intp the catalogue shows that it was replaced by a 529 type unit, probably to comply with legislation of the time.

The second photo, also from the Lucas catalogue shows a sketch of the lens assembly and the third is from Pitmans Book of the BSA which is a useful source of information. Ignore the text on bulb changing which is for the headlamp.

Thanks for the info.
I would like to see a pic of how one is fitted on the number plate, I have seen them inserted from the back which seems wrong.

Two different units.
