The very simplest option of them all is to choose a skin that's fully finished in all details, markings, unit insignias and anything else, including a swastika on the tail for German planes or the national Finnish swastika roundel.

You can't change the numbers around on such skins or make a matching flight, though many skinners do provide complete flights of aircraft with all markings included.

It's a fast and quick way to get all the historical markings correct.
