This model set traces the history of Caterpillar 12 series Motor Graders.  It includes models of the No 12 and 963K, and also a book describing the history of the motor grader series.

This set as one of Diecast Masters Evolution series.

Packaging

The set comes in excellent packaging.  There is an outer sleeve which covers a high quality box.  The box has a hinged lid with a ribbon restraint.  Inside the box there are reprints of relevant marketing sheets, and various photos of  motor graders in the series.

The review set had no missing parts or defects.

A mini catalogue of the Diecast Masters range is included together with a leaflet describing how to install the operator in the 12M3.

Detail

The set includes a comprehensive ring-bound book.  It is full of information from the Caterpillar archives and describes the evolution of the motor grader.   It is an excellent reference work to accompany the models.

The models are fixed to a base plate which has nice quality badges embedded.  The models are fixed by screws with stands.  The stands are partly visible when the models are mounted.

The No 12 has old fashioned tyres and wheels at the front, and behind them is a raking tool.  The rivets used to connect parts are painted so they do not spoil the look.

The moldboard is simple and it is attached to a nice toothed gear ring.  Mechanical connections run to the operator's controls. 

The operator's area has replica levers and it is nice to see an operator which is is fixed in position and is in period clothing.   A plastic umbrella provides protection.

At the rear the engine block and radiator grille have details highlighted with paint.

The 12M3 has nice rubber tyres which are mounted on plastic wheels.  The mud guards are all soft plastic.

At the rear the ripper is metal and the five shanks have nice teeth.  The rivets are painted so they look unobtrusive, and hoses are modelled.

The engine block has metal grab rails and the grilles are formed of graphics.  No hydraulics are visible at the steering pivot point. The cab roof is plastic, and the detail throughout the cab is good and it the operator is in the usual modern style. 

The front end has a counterweight fitted and the drawbar and circle are modelled very well.  The moldboard has rivet details on the blade. The detailing of the hydraulics is very good.

Features

The No 12 has working steering and the front axle oscillates.  The rear wheel pairs also oscillate.

The blade can be rotated.

The 12M3 front axle has very limited steering capability but it is able to oscillate up and down.  The mechanism to lean the tyres is modelled, but was non-functional on the review model. The rear wheels are in linked pairs with very limited oscillation.

The grader can steer across the pivot point behind the cab, but the angle is shallow.

At the rear the ripper can be raised and lowered.

The moldboard has a full range of movement.  It can be raised and lowered, and a small amount of side to side tilt is possible.  It can also rotate on the circle, be extended to one side or the other, and have the face tilted forwards and backwards. 

Quality

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

The presentation of the set is excellent.

Price

The set is good value.

Overall

This latest set in the Evolution Series continues the high standard of the first offerings.  In particular the book is of particular interest to anyone with an interest in the real machines.
