Hunting Clan were quite a large airline in the UK, 1942 - 1960, they were part of the merger that formed British United Airways on 1 July 1960.
They operated trooping flights to Singapore, Hong Kong, Aden, Nicosia and Niarobi with Britannia aircraft.
Two new Britannia aircraft were ordered in 1957, G-APNA and G-APNB were delivered 10.58 and 12.58 also G-AOVA on lease from Bristol Aircraft.
These were still in use when the merger took place, I can still remember seeing them trooping from Stansted, occasionaly after the merger, in Hunting Clan colours.
