WANTED! Caterpillar 660 Coal Hauler Specsheet & PDF file & Action PICS

I am looking for the original specsheet or else a PDF file with the technical background information and some nice action shots or Youtube videos of the Caterpillar 660 Coal Hauler to add it to the model review which will be added on my website caterpillarscalemodels.

As you know very soon a magnificent scale model of the Caterpillar 660 Coal Hauler made by CCM in 48^th scale will appear and so I am busy looking for information of this machine to make my review so complete as possible.

Can you help me? Please send your information to: 

info@caterpillarscalemodels.com

Thanks for your help!
