Could not see date of photo of MOD(PE) lineup, but during 72-75 at RAE Farnborough, we had a heavily modded B(I)8.
Used to have fun arriving at any RAF airfield on a visit, on board a T4 or B(I)6, to dismount and watch the eyes of the groundcrew widen when they realised that the cab had been modded for single crew (pilot that is
) operation. From memory, all that was needed was the re-positioning of a couple of switches to the front end.
Incidentally, they tended to have a better nav. fit than most operational Canberras - VOR and Decca, to name 2, - in addition to the usual.
