We've been through this before. When Hunting was being absorbed into BAC it was decided to rework the 107 around the RR Spey engine and my understanding of what I remember being told by Heinz Vogel was that 111 was the next available Hunting type number.
Before all that was Airco which consisted of de Havilland, Hunting and Fairey and the original Trident was an Airco project, albeit with a DH type number.
