The Esterbrook 'J' series 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.
Introduced in 1948, the earliest pens, such as this example, did not have the 'R' imprint, for registered trade mark, that was added shortly after launch.
The pen is finished in 'Solid blue', the vast majority of Esterbrook J pens have a mottled finish. It has an excellent surface and a very clear barrel imprint The 'double 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.
A new ink sac has been fitted, as the old one had hardened with age, and the pen has been serviced and tested. The nib is a 2314 M', Esterbrook listed the 2314 nib as an oblique, it is a stub point with a slight angle. If the nib is oriented to the left it produces line variation 'naturally', in the right hands it could produce some very attractive results, and it is fun to experiment with.
I have provided a new case for the pen, it is high quality and shows it off quite well.
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 good build quality make the Esterbrook J very practical and durable pen.
