G-AUTO was only ever used on the one Conquest between 1979 and 1984, when it was sold to another business.
Think it was unique in being registered in the G-AU sequence, other than aircraft registered in Australia between 1919 and 1929...
Two registrations that have been used by more than one aircraft were G-BCSE, a CSE Learjet and Navajo; and G-BJCB, two different HS125s. Various period registrations which were either unallocated or allocated to aircraft which never flew with them were reissued to various classic imports in the 1980s, notably Luscombes. For some reason an Aerostar managed to gatecrash the party and was allocated G-ADRW...
