The La-5FN is the aircraft of Captain Pyotr Likholetov of 159 IAP, a 25 kill ace. The slogan on the fuselage reads "For Vaska and Zhora", two ex squadmates killed in action in 1942.
I picked it because I liked the idea of doing a plane with a slogan and there were a couple of good photos of it. The three profiles I found of it completely contradicted each other WRT colours. I went with the one I found in "Soviet Air Force Fighter Colours" by Erik Pilawskii as it seemed to match the photos best.
