Type R47 headlights

[Scarlet O'Hara]

Hi, would anybody be able to post some pictures of the interior details for Typr R47 headlamps and how the reflector is held in place?  All I've got in the shells are three lugs as shown in the attached, I'm guessing there must be a spring arrangement possibly?

There were two types of R47. From Stuart Joseph, an expert in these matters: "R47s have variations, some have pilot bulbs some not. Earlier ones have a reflector with a deep rim that engages in three spring-loaded slotted components riveted to the bowl. Later ones have a reflector with a narrow rim with three slots that engage with three spring-loaded fingers attached to the bowl." Judging by your photograph, yours will have a narrow rim reflector. No doubt our lamp expert, Stuart Joseph, will tell you more. The pictures below show the deep-rim type. The narrow rim type must have been rather cheaper to manufacture.

From Stuart Joseph:

“ R47 reflectors. There are two methods of mounting the reflectors on R47 lamps, the ‘deep return flange’ as shown in the earlier photos and the ‘narrow flange’ which locates on three spring loaded ‘fingers’.
A R40 shell has been used in my pics but they are dimensionally identical.
Regards from the creative county Staffordshire.”

Thanks for all the photos, now that I now know what the missing bits are I'll have a go at making some, unfortunately my reflectors have been trimmed so that's going to be another problem!

I made the “rounded” internal fittings when I converted a pair of R40 bowls. 
Blooming fiddly but by the time I was making the last couple of fittings I was reasonably good at them, not that I fancy ever doing it again.
