Similar wheel with similar stats. These aren't as much in the UK. The blindo ones look a little bit different, each section between spokes is the same size and completely uniform but if you're going for looks these would be a cheaper option I think. It's possible to get some as take offs from military surplus. But I've only ever seen three total at any of those places and one of them was half torn apart from what would have to have been an explosion.
I bought 10 of the Dakar wheels from John Craddock for a decent price but don't see them on the site anymore. Paid 130 per wheel so about $200 instead of the $299 Roversnorth is asking.
