RAD Men with He 51 of Fliegergruppe Döberitz

Men of RAD (Reichsarbeitsdienst) are shown around one of the Heinkel He 51 biplanes at Döberitz - presumably aircraft of Jagdgruppe / Fliegergruppe Döberitz. The He 51 was produced between 1934 and 1937, starting 1936 was partly replaced by the Arado Ar 68 and starting 1937 extensively replaced by the Messerschmitt Bf 109 as a Luftwaffe standard fighter aircraft. At this time, the Fliegergeschwader Döberitz received the distinction "Richthofen", but received the final name "JG 2 Richthofen" only on 1 May 1939, under which it later participated in the Second World War.
