Had a couple of questions on this, the brake is fitted to the F4 forks as in the picture and of course the hub isn't on as the frame has the spinergys fitted to keep them safe. I'm going home tonight so will find out the hub and disc and take some photo's.
I've got no idea if the brake can be fitted to the rear or not, but the hub I have is a front one.
I have loads of other bits to list, will sort them out later. Just had half an hour free last night so started the listings.
