Made between 1948 and 1952, the Esterbrook SJ is the slightly shorter version of the J series pens. At 14.5 cm. when posted, however, it is still a good sized pen.
The pen is finished in a most attractive mottled pearlised green colour, with stainless steel trim and twin black end jewels. It has a good surface, a deep shine, and a clear barrel imprint.
In great condition, a new ink sac has been fitted, as the old one had hardened with age.
The pen is fitted with a Hunt Co. fine nib, these were made specifically for this pen and were a popular option as a replacement for a particular point. This nib is fine to extra fine, it was often used for drawing. It is a great writer, remarkably smooth for such a fine nib.
The stainless steel trim, thick celluloid, and excellent build quality make the Esterbrook SJ very practical and durable vintage pen, it would be a very good daily writer. I particularly like the fact that, due to the unpredictability of the mottling effect, no two pens are exactly the same.
