For more general notes, see the page for the Imperial line.
With its all-metal exterior, this model is not only so splendid that it ascends above the other Imperials’ roman numerals, it is actually a trim level the PFM never achieved. It is not, however, the pinnacle of Imperial achievement, since there were a couple models which are not merely plated but of solid precious metal. It was, if I am reading my resources correctly, the apex pen during the years of the Lifetime badge, during which period it was not saddled with such an oppressively grand name.
While one is not likely to do so, one must be cautious in casual conversation to avoid confusing this version with the much later and frequently rather less splendid Triumph Imperial.

Sheaffer Imperial Triumph, whose name sounds rather like something you’d need a Ceasar in the room to accomplish.
