Oddly, discs seemed to appear on the track quite a while before deep section fronts (see loads of old pix of people with disc rear/box section front), so there are not a lot of deep rears about with track hubs. You are much more likely to find an old Zipp 440 on a road hub, which you could then re-lace to the track hub of choice.
