Here are the models that I like the most:
Chance Vought F4U-5 Corsair Armada Argentina. It's the Hasegawa F4U-5N with Phoenix aftermarket decals.
Airfix's 1:72 A-4Q Armada Argentina and Hobbycraft's 1:48 A-4P of the Fuerza Aérea Argentina.
Airfix's 1:48 Canberra as B-109 from the Fuerza Aérea Argentina:
And finally, a what if Ta 183 in Argentinian markings. This was inspired by the Pulqui 2, aircraft built according to Kurt Tank's plans in the Fabrica Militar de Aviones in Argentina after WW2.
