Here is the most known photo of ZX-6. Note the incorret profile (again!):
Planes
The six-stub exhausts are usually seen on late clipped and cropped MkVb and Vc aircraft in England in 43-44, rather than in the Med.
I know, but 318 Sqn was not just a fighter sqadron as other spitfire eqiuped Polish units. It carried out maily a low level recon task. This photo was taken in Italy at the end of 1944.
This is my text translation. Enjoy...
Markings types:
(1) - Standard Polish marking used till September 1939

(3) - The mark used on some Polish aircrafts in France on 1940 (rotated square with reversed colours)
(4) - The mark used on some Polish aircrafts in France on 1940 (there is overpainted French roundel still visible under red squares)

The markings painting:
The national markings (1) were painted on upper and down surfaces of the wings (for biplanes there were painted on the top of upper wing and on under surface of the lower wing) and both sides of the rudder. Markings on the top surfaces of the combat aircraft wings were pained unsymmetrical and in different distance from the leading edge. Simplified markings (2) were painted on the underwing surfaces oh the some types of aircrafts (ex. PZL P.7, P.11 and PZL-23) – but there are no detailed regulations known.
The national markings from (3) till (5) on Polish aircrafts in France were painted on both surfaces of the fuselages – mainly in GC I/145 fighter squadron and some training aircrafts on Lyon-Bron base.
The national French markings (6) were left on the upper surface of the wings, as well stripes in national colours painted on the rudder botch surfaces (7). The mark (3) sometimes appear as (4) when French roundel was still visible under a thin layer of red paint. A "incomplete" squares (5) with only white parts painted on the French roundels also were used.
