Hi,
Here’s one question I can answer after having gone through frustrating times trying to get the paint code also. Caterham seemed to be less than willing to help out. You can buy small pots of matched paint from them, but not an aerosol.
Tony Weale’s excellent book lists the colour as “ICI 0438 (Post Office Red), B.S. 538”. However, I could not find any paint shops that could recognise this coding, and apparently there are several “Post office” reds.
In the end, a helpful motor factors in Slough mixed me a tin, the formula for which was
TB 40-61.0
11-65.3
54-82.4
59-101.7
I’ve no idea what any of the above means, but it provided me with a perfect match (as far as I can see) against the paint on my ’91 SuperSprint.
Hope that helps,
Michael.
