(On hold) This is a late 1940s Esterbrook SJ in Foliage Green celluloid, with a stainless steel, iridium-tipped 9668 (M) 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 (by hand). The pen measures 4.8" capped and 0.43" in diameter.
The phrase I wrote comes from an Esterbrook advertisement, and it epitomizes the famous fountain pen perfectly. A beautiful, no-nonsense, versatile pen, compatible with a plethora of interchangeable nibs of just about any width and grind you could imagine. In short, a complete fountain pen system. The Esterbrook model gave rise to numerous pens over the years, and for good reason. Very few pens, vintage or modern, can boast such a seamless marriage of performance and value.
Today, you can find a cheap Esterbrook on eBay, but, chances are, it's going to need work. Why take the risk, if you can buy this gorgeous SJ, in Foliage Green celluloid, and with the top-of-the-line M nib, restored and in mint condition? Come to think of it, why buy another TWSBI or a Noodler's Konrad? This Esterbrook will make a fantastic all-around, daily writer, a perfect EDC pen. It'll perform flawlessly, giving you a silky smooth, generous line (0.5 mm on my paper) and a handsome appearance. If you don't yet own a vintage pen, this would be an ideal pen with which to start your vintage collection.
