The S 29C in the Airfix issue?

If you have the Airfix issue of the Tunnan (and not the Heller one) I assume you meant the camouflaged S 29C of F11. Those aircraft had the same top side colours as the Draken, lower surfaces were bare aluminium.

Approximate match:
Olive Green 328 - somewhat more grey than FS.34064 (Imagine a slightly faded Humbrol 116)
Dark Bluegrey 438 - slightly brighter than FS.35042 (a dark sea blue shade)

That gives a bit of room for experimenting with Tamiya or Gunze mixes, but one thing to keep in mind is that the colours often faded or developed various tints over time. Often within a very short time!
The original finish was flat with a slight tendency towards a satin look, within a few months in service though it was usually dead flat.
