Thanks exAscoteer; for your supportive comments on the Jetstream. At the time (1974 ish') it was really "that-or-nought" as the M.E. trainer, or the MRVA (Must Refurbish Varsity Again). There was a political/industrial aspect as well but the type was saved from the Handley Page debacle to go on to become the modestly successful J31/J41, many of which are still operating today. Its then primary rival was the Kingair 90/200 Series which of course is now doing the M.E. training job at Sleaford Tech. Though a well-proven airframe/engine combination, and in use in the M.E. training role by the U.S. Navy, that presumably wasn't chosen for the aforementioned political/industrial reasons?
