(On hold) This is a mid-1940s White Dot Sheaffer Triumph Valiant Tuckaway in striated Marine Green celluloid, with a wide gold-filled cap band, and a 14k gold, two-tone, Triumph Lifetime Fine nib. The pen has been restored, which included a complete disassembly, a gentle cleaning, an overhaul of the filling mechanism, ink flow adjustment, a nib tune-up, and a gentle polish with a soft cloth (by hand). The pen measures 4.48"capped, 5.15" posted, 0.4" section and 0.45" barrel diameter. The White Dot is located on the top of the cap.
Sheaffer designed the Tuckaway to be a "lady" pen, which was fairly common at the time. Today, however, pen companies use a very different narrative for such "pocket" pens, but the fact remains these pens are incredibly practical, and, hence, very popular. If you're a fan of the Kaweco Sport, a TWSBI Mini, or a Stipula Passaporto, you're going to love the Tuckaway.
To me, personally, the Triumph Tuckaway is the perfect pocket pen. Designed to be, equal parts, beautiful and sturdy, the pen excels at practicality and sheer performance. Capped, it will fit in your pants pocket, your purse, or backpack, but when posted, it converts into a full-size pen. In its posted configuration, the Tuckaway has fantastic ergonomics, measuring about 0.51" in total length, with a very comfortable section of about 0.4" in diameter, which makes it nearly identical in terms of proportions and "heft" to the Pelikan M800 unposted. If you write with your M800 with the cap off, the Tuckaway is going to feel very comfortable in your hand, and with the portability that those larger pens are often jealous of.
The pen's functionality and performance are first-rate. The vacuum filling mechanism is efficient, holds a lot of ink, and it's a lot of fun to use. The ink window lets you gauge the remaining ink level with ease. The section has a subtle texture, so a secure grip is always assured. The cap merges with the body seamlessly, with excellent balance in the hand. The large nib extends the section, giving you an incredibly versatile pen in terms of grip. Add to it the Triumph nib's large sweet spot and forgiving nature, and you have a superb writing instrument, able to accommodate a broad variety of grips, holding angles, rotation, and writing pressure. I am not sure I'd be able to find a modern pen that can boast such a combination of features and performance.
The pen is in beautiful condition. The shimmering, gleaming celluloid has awesome depth and vibrancy. The gold-filled trim is spotless, and the imprint is strong. It's a pen that should satisfy even the most discerning high-end collector, but it will give a dedicated writer lots of joy and performance to match. The nib writes a Fine line of about 0.4 mm (on my paper).
