Right, an update.......
After much research it seemed that there were 2 different Evolution Rage 210 3's, one with accessories and one without (possibly other differences as well). This was based largely on images and descriptions. However, after calling Evolution (v helpfull), they advised that no model comes with these, and that the only difference is that one is largely flat pack, the other fully assembled. So ended up canceling the Tesco order, and picking one up from Screwfix for £99.99. Accessory pack only £9 delivered from Evolution, so done deal!
Anyway, thanks to everyone, cheers!
