1. Cockpit colour: green or grey (GAC), for green I have seen FS34272 or FS34558 quoted and have the Humbrol Starmer mixes for both.
2. Wheel wells would they be green or the underside colour.
3. Undercarriage oleos (legs) aluminium or underside colour.
4 Inside of the undercarriage covers green or underside colours.
I have seen RLM65 quoted for the front of the propellor blades (black at back), it looks close to the colour in the photos that I have seen of real examples.
Here is my subject.

Cheers
