Can tell me if there are any decals for Spainsh Huey's in Famet service as I would like to do a UH-1 in whitch I work on in my time in the Spanish Army as a gunner.

Check out Fireball Modelworks. I don't think he has any decals for Spanish Hueys, but he does have some for Spanish Navy AH-1W Cobras that you might be able to use.

Good luck.

You could see if the portugese decal company Carpena Decal has printed any decals for this subject, they have done a few Spanish aircraft decal sets.

Even though they usually focus on Latin American subjects, you could see if Aerocalcas or Aztec decals has a set. They have on occasion had some decal sets for aircraft in Spanish service.

I did a search on the Squadron site and came up empty. Maybe the Hannants site can help you.
