This prototype of the military variant of the famous plane was beautifully restored by SimlyFin based in Staré Město. Restoration finished by the museum enthusiasts in the Slovácký aeroklub hanger. Before the conversion, this Z-137T was registered OK-PJD. Found in Hungary in August 2016, partly dismounted, in a very bad shape. Rolled out to its new career on June 24th, 2017, now an exhibit in the Kunovice aviation museum.
