I think that if Ilford could have bought the machinery they would have, but they've said it doesn't make financial sense to do so. So I doubt anyone will ever make 127 spooled with backing paper again. However Ilford did do a 46mm bulk roll run this year, and I and others bought 50 feet rolls to re-roll. Also I haven't had any trouble in my Yashika44 with the efke take up spools that are plastic... what's the issue?
Next year you can get in on the bulk roll purchase. 11 more months to go...
As for the purple... why not call them to ask, or wait till you get it, no point in theorizing, but I WOULD like to know if the base is clear or orange... if I could get some clear stuff I might x-process it in E-6
