no clue about the model, just typically Scott had some continuous names like Boulder, Tampico, Yecora etc.
Just want to give a hint with regards to the year. It looks like having an LX drive train with HT2, and an Manitou Axel fork, if I'm not mistaken. Both are from 2005 year.
The Boulder below from my 2005 brochure seem to have exact same components.

Still a bike matching the one shown in your picture is not at all in the brochure. But maybe this has bee a model for some specific markets or was not at all in the catalog?
