I found this photo while looking for details of a couple of my old postings in Germany.
I remember that the British Army took over from the Canadians in the Iserlohn, Hemer, and surrounding area in late 1970/early 1971. I was attached to 2 Field Regt R.A. in Peninsula Barracks, Deilinghofen for a time
It was found on:-

There is also another site that shows a lot of photo's related to Canadian Forces in the Ruhr area:-

I know that these have possibly been posted before, but thought they may be worth another look for some people

P.S. Geoff, Mackenzie King Barracks is mentioned on the top site, but it gives little detail.
