I received as a present a 1/48 Hasegawa Mustang, the Hunsdon version, which is basically a P-51K, as shown on the instructions sheet, with RAF roundels used to depict a Canadian or Australian pilot-flown aircraft
Since I don't feel like painting it in a natural metal finish (and above all because I don't have availability of Alclad products, nor I want to poison myself with that stuff ) I would like to know whether decals to make alternative (non NMF, but camouflaged) schemes, such as the Salvadorian ones, are available.
Thanks for any answer and have a nice day!

bare metal foil (tm) or just kitchen foil&white glue, is an alternative to Alclad. I've never tried it but will with some little jets I got in the post yesterday.

Here's an example
