Thanks for your help guys - having done a quick Google search I can see that it is indeed the new XLR Carbon chassis. I wasn't aware if it's existence as it doesn't yet appear to be up on the XLR website. Cheers.
It appears on the Spurh webshop, and seems at first glance to be similar to the EXO 700. However, it differs in several ways, most obviously with its tubular forend. Any advice you guys can offer would be gratefully received...
