Here's the reference photo from my collection (ie does not appear in the article) and 'my' caption by way of comparison..
On May 5, 1945, Czech Radio called on the citizens of Prague to rise up against the Nazi occupying force and for five days Czechs took up arms against German troops until the Red Army arrived in the capital on May 9. Elements of JG 300 - attempting to fall back to Prague from southern Germany - were caught up in the fighting during the uprising. This particular Dora was on strength with Stab./JG 300 and photographed in Prague in June 1945. Kommodore Günther Rall's Geschwaderstab had re-equipped with the Dora in late April 1945. It is unlikely that the former JG 52 ace ever flew a combat sortie in a D-9 during his brief tenure of JG 300. Given the shortages of fuel in the last weeks of the war, sorties flown by JG 300 Doras comprised a handful of training circuits and strafing missions against US spearheads pressing into southern Germany. 'Black <4' displays a representative 211xxx series camouflage finish with a solid RLM 83 dark green engine cowling and an over-painted area of RLM 75 on the rear fuselage, with wing upper-surfaces finished in the standard 75/83 Focke Wulf scheme.
