Interesting thread, Sophie.
I have to say that from size and weight, I had always regarded my Jester and Fantasy weights as potential super-magnums, but the dividing line is certainly debateable. my Jester is marked 1988 and is 116mm diam, and 99mm high, with my 1987 Fantasy being 117mm diam and 96mm high. I also have an un-named weight which has a similar but more rounded, taller profile, so gives measurements of 114mm diam and 105mm high,
how about weight as an indicator? my Jester is 1.886KG, Fantasy is 1.877Kg, my un-named is 1.951kg. I would have said they were all super-magnums, but it may be that Selkirk made some as Magnums and some as Super under the same name.
Another Question, What is the term for the next size up? The largest paperweight I have is a Selkirk with a ph cane, (no name again, but a common style) it is 1340mm (approx.)diameter, 1380high (difficult to measure these large beasts), and weighs 3.568kg. !!!!
