A product of several years of vigorous R&D, the Triumph was an utterly modern fountain pen, "far ahead of anything in the field." The Triumph accomplished what had seemed an intractable pen design problem before, namely, a consistent, silky smooth flow of ink, under various conditions, including temperature, barometric pressure, ink, paper, and one's writing technique. The Triumph ink delivery system excels at buffering the ever expanding and contracting volume of ink inside the reservoir (here, directly inside the barrel). The task is accomplished by an oversize ebonite feed with a huge surface area of its numerous fins and, crucially, a large channel running inside it. Sheaffer took advantage of its advanced R&D laboratories to perfect the Triumph, including rigorous testing, by man and machine. The quote I wrote comes from a 1942 statement that accompanied the launch of the Triumph vac filler.
The pen I'm offering today is a great specimen of the Triumph, perhaps its most iconic model. Built from the gorgeous striated Golden Brown celluloid, with a transparent barrel, adorned with impeccable gold-filled trim, the pen is truly beautiful. It's in excellent condition, too, with only very minor surface wear, difficult to see with the naked eye. Functionally, the pen is as close to its factory condition as possible, with an efficient filling mechanism (up to 1.8 ml of ink using the two-stroke method), and superb ergonomics.
The pen writes an XF line of about 0.4 mm (on my paper). It's firm, but smooth, and capable of writing rapid strokes in virtually all directions, including long, swooping curves. Sheaffer's nib grinding technique aimed at providing a point that wrote very smoothly but without compromising ink flow. Today, it's not uncommon for pen makers to polish the nib's writing surface to an extreme degree, giving the point a sense of smoothness, but, often, at the expense of its writing ability. The Triumph is tuned to write at the lightest touch, and that is where it performs at its best. However, it will also take a heavy hand in stride, rewarding you with a line that is as dependable as modern rollerballs. Ink flow is a touch above average in wetness, so you can take full advantage of the broad spectrum of inks available today.
