I've wanted to know about this for a while too.

Buried in my shed, (stowed behind heaps of crap) I'm pretty sure I have got one thats army green - looks like factory paint (similar colour as the body clips were originally) I think that came off a WB van.. I think.

And one that is red (but I dont think its HQ-WB?) wrong length from memory, unless its the sedan? (I've never owned an H series sedan) and I have no idea if it is factory paint.

I did once have a blue one, same style yellow numbers, I swapped it for the red one I think, becuase the blue one didnt fit my HX van. The blue one seemed chunkier, may have had a thinner section on one end -- distant memory.

I think the one in my HJ wagon is army green.

I'd like to know much more about this as well cuase I'm gonna need one sooner or later for one van (an HX).
