Hello ODK History Lovers

A recent article by Mod Alan M has given us another layer of intrigue.

A New Zealand inventor had produced a reel design with a serious and clever spin
on the double helix - a single spiral producing a change of direction; rather than the
more complicated double spiral to change grass throw direction.

This must be original; and it deserves historical recording.
