This Herald Flying Services Lockheed Hudson was photographed at Camden circa 1949. If the date of the photograph is accurate, VH-SMJ can be eliminated as it crashed in 1947. VH-SMK can be eliminated because it retained the standard Hudson nose glazing. VH-SMM did not arrive until December 1950 so the aircraft in the photo is almost certainly the elusive VH-SML.
