BTW. The Norwegian 105 mm is similar type of gun to the British 4"/45 (10.2 cm) QF Mark V and Mark XV, and those guns had an AA Ceiling 80 degrees. The Norwegian guns was a bit different but how much I don't know. But I know they was build as simple as possible. And during the start of the Invasion of Norway they destroyed a couple Germans planes with these guns.
