Trevor - I could not corner the owner of the M10, so I could not get onto the tank and take the pictures you wanted. Sorry. I do, however, have pics of the outside, with detail shots of the various racks and bits sticking out of the hull sides in particular...
For those interested in the BARV, I did manage to get onto that one and took pics of the top of the hull, as well as a 'walk around'. 27 pics altogether.
