An image depicting the Focke Wulf A-6 as flown by Maj Erwin Bacsila, Sturmstaffel 1, Dortmund January 1944 . Note the armoured windscreen , the Ritterfaust Sturmstaffel emblem on the cowling, the armoured cockpit Panzerplattern initially in four pieces. Here the rifle calibre MG 17 fuselage guns are removed in an effort to save weight as was the armoured Kopfschutz. The spinner did not have a white spiral.  ( references Prien  & Rodeike JG 1 & 11 Teil 2, P. 656 ) The first purpose-built Sturmjäger were from the A-7 production run. An Austrian, Bacsila flew with the Sturmstaffel until April 1944 when he was wounded in the arm and subsequently declared unfit for action.  A respected officer with several command appointments he had previously flown as Joachim Müncheberg's Rottenflieger with JG 77 in North Africa. The aircraft used by Sturmstaffel 1 at this time lacked the 30 mm Mk 108 cannon but were fully armoured and wore the standard Grauanstrich 74/75/76 colour scheme, the Sturmstaffel unit badge and the Reichsverteidigung bands edged in white . Similar rings were soon to be extended to all fighters in home defence units. Bacsila had claimed the first officially confirmed victory of the unit in his weisse 7  shooting down a B-17 on January 30 1944. Returning to active flying with JG 301 in the autumn of 1944 he  was  to be one of the last Kommandeure of IV./JG 3 and is pictured in Prien's Chronik in front of his Focke Wulf 190 Dora 'schwarze 1'. He survived the war with 34 victories and may have been awarded the Deutsche Kreuz in Gold according  to most sources.
