Found the same photo in "Luftwaffe at War - Airwar over the Atlantic". Got excited when the caption started, "This out of the ordinary view shows...........". It then goes on to say, ".....the upper surfaces of a Fw 200C-3. Note the MG 131 gun position on the fuselage.It is possible that this aircraft was one of the first of some forty long-range armed reconnaissance and combat aircraft produced but Focke-Wulf. The dotted lines on the wings mark "No Step" lines" Seriously!! This is the only photo I could find of the shortened mount and they mention "No Step" lines. Maybe the mention of C-3 will help someone find the info
EDIT: Again, found the same photo in "Luftwaffe Colours - Sea Eagles Vol.2". Stunned I is at this caption...
Apparently wing walk lines are for more important
I've looked at it closer and my eyes have deceived me. That is in fact the outer engine. The inner one on the right side can just be seen over the edge of the fuselage, the cowl flaps just behind the antenna mast.
