Surely the Atlantic, and then Atlantique, were bespoke MPA and not off the shelf.
The Nepture was also a bespoke design.
The Shackleton was also bespoke although based on the Lancaster.
The P3 and Nimrod OTOH were both extensively modified from commercial aircraft and therefore nearer off the shelf (some shelf).
