Sorry, my first reply had to wait to be moderated. Here is what I posted earlier....
Hi
I was passed these by one of my Argentinian contacts. They are from a series of photos taken aboard MV St Edmund on or around the 15th June, as they embarked Scots Guards from Mt Tumbledown. The date might be wrong, but that is as much as I know. Here are the rest of the photos. Now, whether or not they are all taken on the same day, I don't know, but they give the context. I have asked my contact where he got them from, and as soon as I know, I will pass it on.
And this photo gives the context, with St Edmund on the lifeboat, which I doubt was down south much longer than the end of the conflict....
And I also found this photo on the net this morning while searching for similar photos, and it appears to show the same left-seater.
Back to you guys - a nice little conundrum to solve!
