Damn you Carruthers. Shoulda cropped it closer!
Sorry - I knew, the instant I saw that image, exactly where you were. With the benefit of hindsight, I perhaps should have sent you a PM with my answer, so as to allow others to offer their answers.
I'm actually not too bad at these picture quiz topics - provided nobody sets me up with a Taunton one, obviously.
Carruthers from Nailsea.
