I don't have immediate access to my documents but as far as I can remember, B.E.A used several post-war variants of Dakota Mk3 aircraft converted by Airwork and Scottish Aviation. These were called the Pionair or Pionair Leopard, depending on the role.
The Pionair Class was purely for passenger use and the Pionair Leopard Class was able to be converted quickly to either freight of passenger use.
Pionair: 28 or 30 seater, depending on requirements. Two pilots and a steward plus a radio operator when required. Single main entrance door on port side incorporated built-in steps and a freight hold was located a little further back.
Pionair Leopard: Used as either pure freighter or in a 32 seat pax role. Double cargo doors on port side, as per C47.
