I've started painting it. Using the Canberra PR.3 scheme. Underside will be PRU Blue. Upper is grey but I cannot determine which shade/tint. Any ideas?

Erm, it tells you on the drawing, Medium Sea Grey.
It's not a generic colour, it's one of the RAF's standards and I know that Humbrol do it, and I suspect many others do too.
LOVE the model BTW.
