Which generation Jubille?
Michael Sweatman puts the date of the first at 1974 (?), and the 2nd which is drillium, at 1981 (?). Of course, there are pre-releases for field trials by teams, which may account for true uncertainty on date.
One reason, and there are others, to admire disraeligears.co.uk is that Sweatman disassembled and repaired these things for a long time, cheap oness and fancy ones. On whether drillium was from the factory: Well that's rather like the q.about pantographing, isn't it? You could find pics of several and see if the holes are in the same place on most.
