In 1947 the bus you were trying to think of was the 316 green London Transport double decker that ran every hour from Hemel Hempstead to Chesham the other bus was the blue "Rover" single decker that ran the same service half an hour later sharing the route
sorry it has taken so long but have not seen the thread for years .
my father worked for BOAC at Bovingdon and got me an apprentice post with them and we left Bovingdon in the middle of 1948 when we transfered to London Airport taking our converted Halifaxes [Haltons] with us .
