This model set traces the history of Caterpillar 40 Ton rigid frame haulers.  It includes models of the 679 and the 770, and also a book describing the history of rigid dump trucks, reprints of relevant marketing sheets, and various photos of machines in the series.

The review set had no missing parts or defects.

A mini catalogue of the Diecast Masters range is included.

The set includes a comprehensive 88 page ring-bound book.  It starts with a written history of this series of machines, and there is a large photograph section.  There is also a comparison of machine specifications.  It is an excellent reference work to accompany the models.

Detail

The models are fixed to a base plate which has nice quality badges embedded.  The models are fixed by screws with stands, but the stands are large and obtrusive.  The display would have looked better with smaller stands painted black.

The 769 has nice tyres mounted on detailed plastic wheels.  There are soft mud flaps behind the front wheels.

At the front the grille looks very good although on close inspection it is actually formed by graphics.  The lights
are good.  The cab has plastic mirrors which have an excellent colour match.  The old style graphics have the machine name, Cat 769.  Inside the cab is an operator in older style clothing.

At the back the suspension is modelled well, and there are rock deflectors hanging from the body.  The dump body is all metal with nice side ridges.  The hydraulic rams are two stage with a gray plastic middle section.

Moving on to the 770 and the tyres have a good tread pattern and they are mounted on hubs which have good detail.    Behind the front wheels large mud flaps are modelled in plastic.

The front grille is solid with the Caterpillar name on top.  The cab has interior detail and a usual Diecast Masters operator, and a windscreen wiper on the outside.  There is plenty of hand railing around the cab although it is soft plastic.  Mirrors are provided, and they are also plastic.

The rear axle is nicely modelled and includes tiny safety graphics, and there are rock deflectors. The dump body is cast well with a good representation of structure. The two stage hydraulic rams are similar to those on the 769.

Features

The models can be removed from the baseplate by undoing screws.

As the models sit high on the stands the wheels can be spun.  On both models the steering is functional although the range of movement is limited. 

 The dump body can be tilted, with a reasonable range of movement although the rams were rather looser on the 770 at the low end.

Quality

The models are very good quality with nice paint and graphics.

The presentation of the set is excellent.

Price

The set is reasonable value for two models and a reference book.

Overall

The Diecast Masters Evolution Series provides excellent history on the real machines covered, and the models are nice quality too, although the mounting plinths detract from the display a little.  The 769 is a new model whereas the 770 is a reworking of a previous 772 model.
