Even though there is no ID visible, it is thought that this is the third prototype of the L-410. There were four prototypes, two of which are in Kunovice, one was used for structural testing possibly to breaking point and the fourth is in Kbely.
The Anasal was a two-seat reconnaissance aircraft built in the Anatra factory in Odessa in the Russian Empire and flown during WWI by both sides during the Russian Civil War. The major postwar user of the Anasal was Czechoslovakia with 23 former Austrian aircraft that were used by the military and later in civilian aviation. This is the only survivor of the approx. 184 built and is on display at the Národní technické muzeum in Prague.
