Interesting PV-1

[Duggy009]

PV-1 is Given Final Checkup at Vega Aircraft Corporation Plant in Burbank, California

The pre-painted parts,can one assume they came from another company,supplier?

Fabulous photo! I just love "at the factory" photos..... being in color is even better. Thanks for posting it.

Brand new planes with brand new engines. Pretty cool.

By looking at the PV-1 in the background, it looks like they painted the circle/star before the camouflage blue.
Seems odd.

I think that the nationality markings may be required when flying on a military registration. So perhaps it was needed for test flights, before application of the final colourscheme.

In all if the photos I've seen of U.S. aircraft, they were painted before test flying.
To use a fairly famous photo...

Some assemblies were painted before being fitted to an airframe.

As far as a regulation about national markings having to be on aircraft before test work, I have my doubts. There are instances in the war of aircraft without military serial or CAA "N" number flying.
Generally, I figure everyone was to busy to worry too much about some admin rules.
