Two things, Danny. First shame at missing your birthday, you are still only eight and a half years ahead of mr, and far brighter in the memory stakes, and many congratulations.
Secondly as I think I have said before many posts ago, I was lucky enough to get some 50 Spit hours in during filming of the B of B film, and a fair few of them were back seat driving with no one in the front, only some sort of camera equipment to get gunsight pictures. Often a cameraman would be in the front seat as well. So, yes all the essentials are repeated in the back so far as I remember.
And so far as handling is concerned, it felt much the same as the standard Mk9. My favourite was the Mk2 which I think is still with the Memorial Flight.
Happy days. As my old chief pilot used to say 'Only perfect, Tim, but will have to do!'
