I've only seen Nishy mention them (although others must have done over time). Is there any point at all in even thinking about them? Nishy said he'd like his next brush to be a Wilborg - or even a TSR LE Wiborg might be a possibility. But everything is "Sold Out" on their website. One or two forums in the US have mentions of blokes having ordered or received them in dribs and drabs but it all seems rather elusive, exclusive and pointless.
