Unfortunately a fake serial and never allocated - this is really Czech MiG-21 0313, obtained from the Kbely museum.

This Fishbed-C flew with the Czechoslovak AF as 0313 from October 1965 until July 1990, after which it was handed over to the Kbely museum. It is now on display at this super museum, which is mostly exhibiting military vehicles but does also have some extremely interesting aeroplanes.

22542 is a fake serial, it really is Czechoslavkian Air Force 0313. It is a MiG-21F-13 built under licence by Aero as a S-106. It was taken on charge in 1965. After the end of its operational life, it went to the Letecké Muzeum Kbely where it was first noted in 1990. By Oct-2016 it was noted in Slovenia in the Park Vojaške Zgodovine (Park of Military History) in Pivka.
