Swarb seems to have first appeared at the Topic when he showed up with Martin Carthy on March 11th 1966... almost exactly 45 years before this forthcoming appearance.

(On that day in 1966, according to Wikipedia, Indonesian President Sukarno gives all executive powers to General Suharto, and French President Charles De Gaulle states that French troops will be taken out of NATO and that all French NATO bases and HQs must be closed within a year.)
