As there are potentially many of these I may create a thread specifically for Adoption Plaques later, at which point I'll move your post into it. I was previously chasing photos for two myself which I gave up on, but must take up again. One was for MTB 79, which used to be in the Working Mens Institute at Blaenavon, South Wales, but wasn't there any longer when I visited, and which may now be held by the Library.
I recall Google Newspapers has a lot of UK newspapers that were in existence during the war, digitised, and they quite often report on adoptions. It would be good to but together a definitive list at some time.
also lists some.
