Beech 1900
The CAA took a dislike to the original B1900C - which was effectively just a stretched 200. The 1900D with the greater headroom was looked at by Alan Mann (when they were Beech/Raytheon distributers) for being put onto the UK register but I think the fact that the UK market was small and they could, at that time, sell as many 1900D's as they could make, made it uneconomic.
The fact that there was a UK manufacturer selling a competing aircraft (J31) was probably just a coincidence? Despite that fact that the 1900D was a far superior aircraft, with large freight door as standard, and you didn't need to be double jointed to side in the window (huh) seat in row1. Not Invented Here - never came into it!
