Below are links to an actual wartime newsreel about Little Norway. It is a bit slow to watch in parts as there is a lot of travel log footage to get people unfamiliar with Norway up to speed. I did not see a production date for this, but it is some months before Pearl Harbor. During the mid 1940 through 1941 time period, there was a fund raising campaign in the States called "Wings for Norway", and this film is part of it.
As far as A-2s....only a few quick views on the flight line, but there is some very rare color footage of RNoAF planes and troops training. Most of the flight gear these guys are wearing is either RCAF or commercial US. For example, the battledress, flight suits, and helmets are RCAF, the goggles are American commercial....and the A-2s....probably commercial versions as well, since many things were purchased on the open market with funds raised during the "Wings for Norway" campaign.
