Nice! Shackleton is pushing it ('46 requirement, '49 first flight), but the others are all '46 aircraft, '45 in some cases.
Aye, but just perhaps in some alternative world the lessons of the Great War were actually learned and the protection of British trade was taken seriously from the start. Not likely but it can be fun to wonder sometimes.
On reflection Shackleton could easily have been speeded up, it's essentially a Lincoln with an alternate fuselage, and there was a glut of Lancaster/Lincoln alternate fuselage transport versions - York, Lancastrian, Lincolnian, Tudor, Jet Tudor, and Ashton - being worked on that could have seen work diverted into an MR variant.
