No, sorry Roger. Not Seaton. I couldnt find a photo of him either.
You are though correct as to the topic, I think.
But the person that I am referring to has no connection with Seaton. My person, when he was involved in the topic of interest, had no mustache. He may have wanted to have one, but I think I'm correct in saying he did not have one.
There's a very indirect connection with this person ...
With that near 'Finish', I think I have either given it away or totally confused you.
