Hello Philou;
This was likely a Meteorologist Observer (taking Weather notes and measuring temperature, humidity, Barometric pressure etc); but also observing enemy activity if seen ... his plane was this below. Code
D7+F
K is of ´Wetter Staffel 2 (but Wekústa is also correct).
W.Nr. 0881141 Ju 88 D-1 Wekústa 2 (Luftflotte 3)
