One of the most successful racer cruisers from South Africa during this period. Most but not all came from Nebe in South Africa.
The deck shape evolved from the flush foredeck of the earlier models, to a more extended (forward) coach roof in later versions (shown here).
Interior layouts and other details vary widely.
