Okay chaps
I've been checking out this colour issue and I'm now not sure where to go with this.
I dragged out a few of the components that need to be sprayed and the horn push and the indicator arm appear to be L75 Light Beige - they have a slightly browny \ tobacco colour to them as this colour does, but the handbrake lever, steering wheel and seat frames are definitely a different lighter colour - more an ivory \ ivory grey colour, which is why I suggested L82 Silverwhite originally.
Now the seats are definitely original and I think the steering wheel is, both of which are the lighter colour (and the colour I like better actually) but I can not guarantee the horn push is an original and I'm pretty sure the indicator arm is a spare I have as I already primed what I think what was the original.
So has anyone got any more ideas now on what the lighter colour might be?
I did try taking some pictures but my camera battery run out. I'll try get some pictures up soon showing the different colours.
