There was a recent article about the Skyways DC-4 charter to BOAC by Peter Marson in Propliner magazine #121(BOAC and the Speedbird symbol were painted near the pax.door in addition to the Skyways paintsheme)...I think the Skyways DC-4s came from the batch loaned to the Dutch before their 'proper' civil-built fleet arrived
