When we painted a Slingsby Kirby kite 1 glider in its ww2 markings we had to get permission from the MoD. We are now painting a German Grunau Baby 2b glider in ww2 markings we got permission from the German air achecte in London.

Although the application process is triggered by your initial request to the CAA to not carry a G registration. They are fairly relaxed about RAF and US schemes bit anything else is usually reffered to the foreign powers represenatatives in London for approval as you discovered.
