Andy,
your right that the pictures don't show the faceted ones, but VWP did them last time I spoke with them.
I'll look through my links again, as I know they are abvailable, I've brought them !!
The white ones I have came from an autojumble (they are new), and I should have the card for the supplier somewhere, probably take a bit of finding though...
According to my notes, Lucas part numbers are:
Green - 38102A
Blue - 38103A
Red - 38104A
white - 38105A
Amber - 38107A
