[7] Eight others were sold back to Blackburn Aircraft, three being converted with a glazed cabin for its subsidiary, North Sea Aerial Navigation Co Ltd, also based at Brough Aerodrome.

In the first few months of 1919, most of these converted aircraft continued to fly (and sometimes crash) in military markings, then the survivors were repainted with civilian registrations and commercial titles.

In May 1919, joy-riding, cargo and passenger charters took place at locations including Brough, Leeds, West Hartlepool, Gosport and Hounslow Heath.

During August 1919, three Kangaroos flew to Amsterdam for the ELTA air traffic exhibition and spent several weeks giving flights to an estimated 1,400 passengers.

[12] A single ex-North Sea Aerial Navigation Kangaroo was purchased from the Aircraft Disposal Company run by Handley Page in July 1921 for the Peruvian Army Aeronautical Service, paid for by private donations.

It entered service in July 1922, but after the departure of the British military mission later that year, there were no pilots qualified to fly the Blackburn, and it was scrapped early in 1923.
