Hi guys.
Without a shadow of doubt this is Herdla. Take a look at this photo which shows the Gefechtstand of 3./JG 77 at Herdla in 1941 in more detail. This is the same building which can be seen in the upper left side of the new photo.
Note the building to the extreme left in the photo above - it was a moveable small hangar made to resemble a barn, except that barns in that construction style did not exist in Norway!
The dark camouflage of the Emils are noteworthy, this was a feature of many of these aircraft.
Regards,
Kjetil
