Correct color code

Posted by TWB On 2013/11/11 16:54:57

I have been told that the French Blue colour with vermillion red wheels is color code 'Z' for 1939. I now see from this site info that the 1940 option was 'S'. My VIN plate shows manufacture date a nov 8, 1939. However registration was 1940. So my question is which color option letter would be the correct one ? Thanks
