Ah... The Scottish Flyer , an attempt at a "bus stop " service. If memory serves me right starting at Southend routing , Stansted, Luton , East Midlands, Leeds and other stops to Aberdeen? Then back again all outside Controlled Airspace using Mil Radar. Mainly Viscounts , did one have "Scottish Flyer" on the fuselage? Also at least one trip with a 1-11. It couldn't have made money and didn't last long. I remember a Viscount making at least two attempts to land at Luton in poor weather to pick up one piece of 20kg freight. All load info passed through ATC :-)
