This example is on display at the Letecké Muzeum Kbely in the markings it wore at the Aviation School Prostějov in the early 1950s. It then flew with the Praha Točná Aeroklub as OK-DJR and was eventually sold to a private individual before becoming part of the National Technical Museum. It was handed over to the Letecké Muzeum Kbely in 1968 andcompletely renovated before going on display.
