Anyone ID the people in this picture.

They all look familiar, I think the middle person is Michael Palin, (certainly looks like him), but what about the others.
Did not recognise them when I took the shot.

I saw the guy who is the spitting image of Michael Palin but I don't think it's him. I'm guessing he's a mechanic.

It's Frank Meakin in the Blower, and the others are Bentley Motors mechanics - not Michael Palin
