I was watching an old episode of the TV cop series from the 1970's 'The Sweeney' the other day. Quite a lot of Fairoaks features, the West Entrance in particular and a scene when an AMH Bell 47 fly's over; I can not see the registration; but she is in the famous white yellow and black colours; can anyone help identify it? The year would have been either 1974, 75 or 76.
