Onoto Model 'O'. Fully Restored. c.1905.

Regular price £295.00

The 'Onoto' name was first used, by the De La Rue pen company in 1905 after the plunger filling system was patented in the same year.  This 'Patent Self filling Pen' was the first pen to be made using the Onoto name.

The pen was made in two versions the 'O', this pen, and the longer 'N'.  The 'O' pen was particularly popular with the military as it would fit into a uniform breast pocket and allow the flap to be closed, a requirement for many occasions.  It was still sold in far fewer numbers than the longer pen and is consequently now a good deal harder to find.

 At 12 cm. when capped, the pen grows to a very respectable 15Cm. when the cap is posted on the barrel for use.  The cap posts securely on the filler button at the end of the barrel, the pen was designed to be used in the posted configuration. 

The condition of the pen is remarkable.  It is constructed in black chased hard rubber (BCHR) with a clear engine turned 'chevron' pattern on the barrel  and a plain cap.  The barrel imprint is crisp and clear, it reads:

Patent Self filling Pen
De La Rue London 

The two wide bands, one on the barrel and one on the cap lip carry an assay mark and could well be 18Ct,  there is no sign of brassing or tarnish.

The nib is stamped. longitudinally, with '14 Carat Gold' and 'Onoto De La Rue'.  It is set in an ebonite (hard rubber) feed with an 'over and under' design.  It writes well, with a firm, fine to medium line.
Clearly, this pen is in remarkable condition and meets all the criteria for an absolutely first rate collectable pen.
