Early Colour Photos of Volmer Sportsman Amphibians of New Zealand

Continuing with early colour photos of two seat homebuilt aircraft of New Zealand from the Don Noble collection, I now post these photos of Volmer Sportsman ZK-EDB. 

I originally posted on Volmer Sportsman amphibians at:

I have gone back and added the second photo to my original post.

At Invercargill, 11/5/75.

At Nelson, much later on in its life, 26/12/98.

I had never seen in in this colour scheme before seeing Don Noble's photo.  Can anyone add anything to the history of ZK-EDB? - it was registered for nearly 30 years.
