My van is a 10/78 originally with 63v trim. I am slowly collecting the 63v bits as I currently have black.
I picked up an arm rest the other day that is supposed to be buckskin but is a slightly darker colour when held together with one of the original 63v ones I removed years ago.

Is the actual colour of 63v different to 63c?
When did they change?
I do remember reading something about this ages ago but can't remember or find it now.
