The 'Fivestar' radio brand was introduced in NZ in around 1947.
Fivestar was manufactured by Akrad Radio Corporation Ltd, they were distributed by G. A. Wooller & Co. Ltd. Currently there are 2 documented models.
The Fivestar radio brand is one of the harder-to-find of the post-WWII Akrad Radio Corporation Ltd. Apparently used to market some non-radio products but often seen as a brand on radios otherwise marketed as Clipper, Regent or Pacific.
