Further to my post on Flxible Clippers Max has let me know that Newmans in NZ also ran six of the Ansair versions. They date from around 1952, but ran into the late 60s, but I don't really remember them.

On the Ansair built flxibles, the winged badge on the front read "Ansair Flxible Clipper"
A preserved example is housed at Founder's Museum in Nelson.
