This model is of the Fun Ho! #55 Tractor Scraper in blue. This model is possibly based on the Caterpillar DW21 of which there were many in New Zealand. However, it could just as easily be any of the other brands of scraper of the time, as many looked the same as this cab-free model.
There are no opening parts on this model. All features are cast into the metal of the model. The model appears to be based on a Caterpillar DW21.
At the front of the Fun Ho! Scraper there is a cast representation of the headlights and grille. Behind this is the "cab" area with driver's seat. Both sides carry cast body lines and representations of the engine and scraper mechanism. The rear is cast to show the interior of the scraper bucket.
There is no interior, however the "interior" of the "cab" has some minimal detail including the seat. There is no glazing.
All wheels appear to be one piece, black plastic, typical of the Fun Ho! miniatures of the time, mounted on steel domed axles. They are a much larger diameter than those used on the other vehicles in the range to better represent the size of the wheels on the real vehicle.
The base plate under the motor appears to be lightly plated. It is held in place by a single machined rivet and its function is to hold the axle in place. This base is marked "Fun Ho!, No 55" to the centre top, and "Made In, New Zealand" on two lines to the centre bottom. A second base on the scraper component, also held by a single machined rivet, appears to be there purely to hold the rear axle.
This is likely to have been a late issue, issued between 1978-82. During its lifetime, 320,000 Tractor Scraper models were manufactured with a paint finish.
The scale is unknown but thought to be around 1:134. My reasoning is that the normal length for the caterpillar DW21 was 499 inches (12.475 metres) and the model has a length of almost 3.75 inches (93mm) (12475/93 = 1:134).
