Ahh, Sierra Victor...
This is how I remember that aeroplane - fifty years ago:

November 1967. Operating the early newspapers and mail to Hanover for the BAOR with Captain Joe Rechka. Gatwick runway closed overnight for resurfacing. Hence operating from Southend instead after a night-stop there - pobably in the Westcliff hotel (or maybe the Overcliff).
G-AMSV, a C-47 Dakota with the Transair landing-gear fairings modification, had come to Morton's from British United Airways and one of that airline's predecessors (probably Transair). Morton Air Services had become part of the Air Holdings/BUA group, owned by Cayzer's British & Commonwealth shipping line, but Sammy Morton's name was retained until Alan Bristow's big shake-up of the BUA group in 1968. With BUA (CI) and BUA (Manx) being closed, Morton's then merged with them to become BUIA (later BIA).
