Northrop N-3PB colour scheme

Hi,

Before the Northrop N-3PB’s were transported to Iceland they were used to train Norwegian air crews in California. I’ve seen a number of photos and I’m trying to confirm the colour scheme.

It looks like Olive Drab over Neutral Grey with possibly yellow numbers. They also had the red/white/blue/white/red Norwegian stripes on the wing and lower part of the rudder.

Can anyone confirm these colours?

Also does anyone know when they were repainted RAF grey/green? Before or after they arrived in Iceland.

Thanks,

Alex
