The 'Beeline' flight line! All but the Viscount, are models from that era. The 1/72 Argosy is an AW factory model, with clear windows. The mint condition Skyland 1/50 Comet 4B, is probably the most prized of my whole collection. The Trident, Vanguard, and Viscount, are 1/72. The Viscount is a recently made model.
