This model set traces the history of Caterpillar 20+ ton excavators and includes models of the 225 and 323 Next Generation, and also a book describing the history of the excavator line.

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  machines in the series.

The review set had no missing parts or defects.

A mini catalogue of the Diecast Masters range is included and there are two parts which have to be fitted.

The set includes a comprehensive 64 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. 

The 3225 has tracks are they are mounted on track frames with static rollers.

The cab has a metal grab rail and the plastic door with a slight colour mismatch to the metal parts.  The interior detail is simple.  An operator wearing older style clothing can be fixed in the cab. 

The body casting has finely detailed rivet heads, panels and grilles.  Detail on the roof includes a straight exhaust pipe. Old style Cat graphics look sharp.  There are textured walkway surfaces.

Soft hydraulic lines are modelled.  Rivets on the boom, stick and tools are painted and an old style Caterpillar graphic is on the boom.

The thin metal bucket is a nice casting with sharp teeth.

The 323 tracks are metal with triple grouser shoes.  They are mounted on decent track frames with static rollers, and there are a couple of tiny graphics on each frame.

The cab has got a plastic mirror and a separate wiper is attached to the cab structure.  There is a metal grab rail and the plastic roof has a window.  Inside the detail is very good with Cat on the seatback and also on the left control console.  An operator wearing bright high visibility clothing can be fixed in the cab. 

The body casting represents the body shape very well and the side grille is formed by graphics.  The Cat graphics are very sharp and there are some tiny warning signs.    On top the engine cover is plastic with more graphics used as grilles.  There are textured walkway surfaces and the handrails are metal with a plastic mirror.

Soft hydraulic lines run to the boom and silvered connectors are modelled. More pipes and hoses run to the stick and again the connectors are modelled. Rivets on the boom, stick and tools are painted and there are small graphics on the stick.

The metal bucket is a nice casting with sharp teeth.  The quick connector is modelled.

Features

The tracks of both model are mounted on spring-loaded idlers to maintain tension and the models rotate well.

The boom and stick on both have a good range of movement, and the bucket movement is reasonably good too. 

Operators can be installed in the cabs for when the model is posed working, or the cab can be empty to represent being parked up.

The 225 has an opening cab door although it clashed a little with the grab rail outside the cab.

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

As the latest in the Evolution Series this set maintains the high standard of presentation of previous sets and it is interesting to see the model of the old Caterpillar 225.
