A somewhat nondescript Junkers W 34 hau during engine start. The mechanic on the left is holding the crank for the inertia starter. The last letter of the aircraft's registration can be faintly discerned, it seems to be a "D", making it ??+?D.
The aircraft reportedly belonged to Flugzeugführerschule A/B 4 at Prag-Gbell, Czechoslovakia; the photograph was apparently taken at Kralupy, in 1940 or 1941. This view beautifully illustrates the enormous span of the otherwise rather diminutive W 34. Camouflage seems to be standard 65/70/71. (German Aviation 1919-1945 collection)
