We're glad to help.
The better term would be "National Insignia" or "National Markings".
The F4F-4 would be a great project for this approach. The earliest deployments I know of were onboard in early 1942, the Hornet had them for the Doolittle Raid. Those were painted with really big national Insigs, with the red dot and with tail stripes.
But at Midway, they were without tail stripes or dots.
And the fuselage numbers changed too.
Here's a muddle of parts I did a while back, all hand painted copy and Hinomarus.
