I believe the Soverign TM had a smooth clip and no white dot, as opposed to a Soverign Snorkel, which has a "Sheaffer's" clip and no white dot. This is the same as that one I sold a while back
here. We scratched our heads about it, but re-reading Jim's article I see it more clearely.
Jim, since this is such a source of confusion, maybe you can add a line clarifying that it is a smooth clip, as the Soverign section of the TM article just says "Gold filled innerspring clip".
