Remarks by Johan Visschedijk: "This Cmelák (Humbel Bee) was registered on August 26, 1974 as DM-SSJ to the state aviation company Interflug of the Deutsche Demokratische Republik (DDR, Germany Democratic Republic, commonly know as East Germany), and was operated by Interflug's Agrarflug (Agricultural Flight). In 1981 the DDR country code changed and the aircraft was reregistered DDR-SSJ.

The registration was cancelled on September 1, 1990, and the aircraft was sold to Flugservice and registered D-ESSJ in February 1991. The registration was cancelled in August 1993 and subsequently it was put on display at the museum 'Flugausstellung L.+P. Junior' at Hermeskeil."
