Sorry for the size...
All gentlemen, you're right a little bit.
In the picture there is Yak-9, but this is not a photo from the war, only a frame from the film "The story of one fighter" which was filmed in Poland in 1958.
The film tells the story of Polish pilots in Great Britain, including the 306 squadron.
The author of the script was a Polish hunting ace Stanisław Skalski who shot down 18 enemy aircraft during the war, and in communist Poland until 1956 he was in prison with a death sentence for alleged espionage. After 1956, at the request of the Polish Marshal Marian Spychalski, he returned to service in the air force, he made his first flight after leaving the prison without training on the MiG jet.
The plane in the picture is in the painting of another Polish ace, Jan Zumbach, from the 303 Squadron.
If you're interested, I can send a link to the movie.
