A total of 86 SM-2 helicopters were manufactured by PZL-Swidnik, with this single example purchased for the then Ministry of the Interior of the ČSSR. It was delivered in December 1962 and served with the Ministry as OK-BYK until 1970, after which it was transferred to Slov-Air as OK-RUV and used to check the condition of power lines and oil pipelines, as well as for film and TV work. The helicopter was retired in 1975 and transferred to the reserve collection of the Letecké Muzeum Kbely. It has been superbly renovated by LOM PRAHA and is now on display in the main museum hangar.
