They were filmed 10 years apart, but both are a bit older, showing Islay 33 and 43 years ago respectively. The first one seems to be some old TV footage filmed in 1983, showing Port Charlotte and a few other places on Islay in a short clip:
Going back a further decade to 1973 we can watch some fascinating old footage with some long gone history, starting with the MV Arran ferry (not to be confused with the MV Isle of Arran, which was much later) leaving from the old West Loch Tarbert pier:
The rest of the film shows a variety of familiar places, some in a way now gone: The Oa with the American Monument I believe before it became an RSPB reserve (not sure which year that happened?). Port Askaig long before it was redeveloped to what it is today. Ardbeg distillery with smoking pagodas. A brief glimpse of what I think is Western Ferries’ MV Sound of Jura. An excursion to Jura with of course plenty of deer.
The filmer seems to have also had some interest in birdwatching. I think there were a number of Whooper Swans (the quality of the footage isn’t great, making it difficult to see) and there’s some footage of the Barnacle Geese as well.
