That's so true Walter.
It would be nice to get a modder familiar with markings to tidy up a few inconsistancies in default markings. In the case of these three examples the sought for effect would add a simple numerical marking to the fuselage, without the 'extra' white stars which are also being applied.
However, this type of numerical marking is also totally unrealistic/unhistoric. If you need a bunch of P-51s for a campaign there are many skins out there. The beauty and variety of schemes for this aircraft is the principal reason most people don't use default markings for the P-51. Flying it without the numerical marking would be just as realistic too.
I would also really like to see the appalling TD-412 RAF Roundels, which have been wrong from day one of the 412 release and not fixed in 413 either, be corrected. There are a number of other problems with the default markings that are in no way down to the individual mods. Its the overall markings package. Its a 412 problem too, so comparisons with earlier versions are not useful.
Anyway I will keep a lookout for a fix. For now we simply have to work around it by using individual skins and proper markings done by the many great skinners of Mustangs. Not too difficult thankfully!
