Description;

Thomas De La Rue Ltd began manufacturing the Onoto range in 1905 and they quickly eastablished themselves in an already densely populated marketplace. The pens were successful because of the excellent quality of the materials used and the superior design of the filling system. Onoto pens were as good, if not better, than all their contemporaries including Parker, Watermans and Conway Stewart.

This is a superb example of the Onoto's "The Pen" finished in Black celluloid with gold filled trim. The pen dates from the mid 30's. This is a very rare Demonstrator version with a large transparent viewing window in the upper half of the barrel. This allows the user to see how the the rubber washer is used to create the vacuum which sucks ink into the barrel when the washer reaches the recess in the barrel inner. It also reveals how the ink shut off device works by observing the conical end to the plunger and the corresponding conical recess in the feed.

The plunger filling system, deliciously quirky but extremely efficient, has been fully serviced with a new washer and cork seals fitted.

The pen itself is in very good condition, the pattern is crisp and the pen only has very minor marks and scratches commensurate with light use. There is a little wear to the plating on the clip but that is to be expected from a pen of this age.

The 14ct gold nib is in excellent condition and writes beatifully with a Fine line. The nib has a nice flex to it which gives a lovely shape to your handwriting.

Onoto pens are fabulous writing instruments and will give years of faithful service.
