Last night I went to see a friend’s Lavender Grey MkIV that is part way through a respray. The above subject arose with me saying that the lightbox frame should be body colour and my friend insisting that his frame is original to the unrestored car and is painted black. It looked a little strange to me but it does make sense that Jaguar would not spend time masking the bought in lightbox so that it could be sprayed body colour. I also checked photos of a known unrestored car and also GVC677, the Autocar Road Test car of 1948 and sure enough they are not body colour. The SS Jaguars use a different lightbox but there again the frame is not body colour.
