Thanks James, will have a look
Re paint colours - Very good news, they were there all the time ! Having cleaned up the partition with a view to using it as a reference for new paint, I then compared it to the colour on the roof.
The roof is so faded it looked the same, but then I compared it to scuttle around the engine bay. It looked a bit different so I polished up the scuttle for a better look and guess what - different colour, so I do have both ! There are 2 greens, but not that different, especially when they are faded, dirty and not next to one another !!!
I had assumed that the interior colour and the roof were the same darker green and we had "lost" the lighter colour, but, not at all ......
That means that the interior and the boot are the lighter colour and not the darker one as I first thought, and the only dark bits are the roof, bonnet, door tops and scuttle under the bonnet. Now need to check the underbonnet colour to see which it is, light or dark ?
Next thing I did was polish up the glove compartment lid so I could put them side by side properly and take a couple of pictures. I don't have a loose panel with the darker colour, so I will have to load the van onto a trailer and take her to a friendly paintshop for the spectro - oh well .....
Final picture shows the partition ready to prevent "Fido" joining us in the front !
