For more general notes, see the page for the Imperial line.
After the big re-jigging of the line in 1973, the name “Imperial” was applied only to the upper end of pens in this family, while the popular-market pens got to be called “Triumph”. This is the very bottom of the barrel of that period, and when I say that I don’t mean to disparage; like something at the Glenkinchie distillery, there are barrels whose bottom contains a certain amount of delight.
This pen is very like the previous Imperial IV in its looks, swapping chrome and steel for the older pen’s gold, and having a shorter inlay. The writing characteristics are also about the same.

Sheaffer Triumph 330 – which I will persist in calling a variant of Imperial
Wood grain! That means it’s the 1970s!
For a low-end pen, this is quite a production. Note that the word “Triumph” does not appear on the box at all; it’s a catalogue reference that provides.
