Treffield was a small airline, started by Lord Trefgarne, with two aircraft (the other being a leased Laker Airways Britannia). British Eagle did the Viscount maintenance for Treffield at Liverpool and Treffield were famous for not paying their bills. On this occasion, just before they ceased ops, British Eagle wouldn't release the aircraft until they paid up-front. Lord Trefgarne duly arrived in a Beagle Airedale and gave us a personal bank draft.
