They are in stock with Hattons and I've had notification it is being packed, I get mine at £17 (plus postage, would have been nice if I could have combined with some other items to make it more worth the postage), so that is a saving on the current price.
Seen the image in Rails, is it worth the is it 2 or 3 year wait, probably not it's only a MKIII buffet but at least I have the full WR rake now.
