Caterpillar Wheel Loader

Hi , i advertised for a Caterpillar 966C and having operated them in the 70;s i know what they are,however someone emailed me a loader which has 966C on the front arms and the engine cover but unless i am mistaken and Cat made a later model 966C the company selling it has got it wrong.So i am wondering if anyone can tell me what model loader it is going by the attached pics....hoping i can work out how to attach pics that is,,,thanks heaps....
