Dornier Do 217N-2/R22 6./NJG 4 (3C+IP) flown by Fw. Gunther Konzac, Taveaux, France, May 1944. This aircraft, W.Nr. 1570, was finished in a splinter scheme of 74 and 75 on the uppersurfaces and while the undersurfaces were 76, the starboard wing had been overpainted black up to a point just short of the leading edge and terminated in an undulating demarcation line. Although the full operational code was 3C+IP, only the last two letters appeared on the fuselage in black with the individual aircraft letter edged in yellow. The spinners were 76 and the propeller blades green 70. Note the configuration of the tail cone.
