The Esterbrook 'J' double jewel series, introduced ain 1948, was made in three sizes the 'J', this pen, was the largest, the 'LJ' was about the same length but slimmer, and the 'SJ' was shorter.
The pen is finished in 'Copper' with irregular striations and swirls, some batches were a darker colour and some more vivid, this is one of the much brighter pens. It has an excellent surface and a clear barrel imprint. The 'grooved' design of the clip is carried through to the cap band and the filler lever, all in good condition. It is a 'double jewelled' pen, with a black stud at the barrel and cap ends.
The pen is in first class, uninked condition and still carries the sticker identifying the nib as a 'Dura 2668 medium firm.' The nib is horizontally engraved, later pens had nibs that were were engraved vertically, it was probably made around 1950.
At 13 cm. capped and an impressive 15.5 cm. with the cap posted, this is a long and very well balanced pen with a satisfying solid feel. The stainless steel trim, thick celluloid, and excellent build quality make the Esterbrook J very practical and durable pen. Although this example is clearly in collectable condition, the filling system works well and the pen is ready to be pressed into service if required.
