Clandestine fligths UK-Norway

[Oyvind]

Bringing agents to/from Norway and UK during the war by means of airplanes, were either by Norw. 333 sqn. Catalinas landing along the coast, or parachuting from "bomber"planes.
However a source tells me that late 41/early 42 one or two fligths were performed using seaplane(floater).
One of the fligths were carried out between Inverness and Stavanger area (east of Stavanger behind an island) in the shadow of a bombingraid at Sola airpoirt. Weather was clear and full moon.
The crew apparantly didn't seem to speak Norwegian so if it was the ex Norw. He115, they used apparantly non-Norwegian crew at times.
If it wasn't the He 115 what could it then be for a floatplane ( Modified Blackburn Roc to extend range (4 were built as floaterplanes), Ar 196 in RAF service, if that existed, or?)

The source seems more to remember it in fact it was a single engine aircraft and seems sure it had floaters.
Does anyone have any clues?

If landing in Inverness or nearby was the case, were there any military facilities or bases in Inverness or nearby accomodating seaplanes?
