Thanks RFCC - now my views can get sensible names instead of Rear 1, 2 and 3. :-)
I did some more focussed googling and found this on youtube - apologies if its been posted before...
YouTube - Victor XL231 Tour 1
and the other vids from Olliemeister.
I now have answers to questions I didn't know I had :-)
I had planned a trip to Elvington as part of this project but with the help of these videos I can postpone it for a while and have more focussed questions when I go.
YouTube - Victor Tanking Sortie Part 1 will also be very useful too.
