The design team for the SOKO 522 was led by a Slovenian and so it is fitting than one is on display at this super museum. This example on display wears a fake serial as in service it was 60123. The frame was on display for some time at the Kbely museum in Prague.

23500 is a fake serial, it really is 60123. After service it was originally in Mostar, but it moved to the Letecké Muzeum Kbely in Czechia where it was noted in Nov-2008. In 2009 it was moved to Slovenia and became an exhibit in the Park Vojaške Zgodovine (Park of Military History) in Pivka. A total of 112 Soko 522s was built, production ending in 1961. It served in the Yugoslav Air Force from 1954 to 1978 as a trainer/light combat aircraft. The type was used in a number of movies, e.g. The Battle of Neretva, or Kelly's Heroes as stand-in for German Fw-190s.
