|Morris Mini Traveller Colour Finishes and Upholsteries, April 1960|
The best thing about the cards is that they have been stored in the dark all this time so shouldn't have faded or discoloured. This will be a great help when it comes to matching the original colour, there were at least three variants of OEW used by BMC in the sixties. Likewise I will be able to compare the original vinyl swatches to the reproduction trim available today.
Once I have worked out how to store the files online, I'll post up a link so that anyone who wants a copy can download them, although the colour reproduction is not terribly good so they may not be much help. I have some parts manuals I'll try to scan and make available too.
