The Parker Duofold Senior was added to the U.K. Duofold aerometric line in 1954, a year after the first aerometrics, the 'Standard' and the 'Demi'.  The Senior was the largest of the U.K. Duofolds at the time, production ceased in 1958.  This particularly fine example carries a date code for the first quarter of 1956.

Finished in blue, the pen is in excellent condition with just light usage marks, it has a very good finish and the gold filling is pristine.  The cap is a smooth screw fit, it tightens securely with one and a half turns and carries a colour coded cap jewel.

The pen has been fully serviced and tested.  The aerometric filling system is easy to use and works well.  The correct 14Ct. Gold No. 35 nib is large and impressive, it has a fine point and delivers a smooth fine line with the pleasing 'soft' feel that Parker achieved so well, even with a fine nib. 

The Duofold Senior is a very large pen, 16.3 cm. (well over 6 inches), in length when posted for use.  It is well balanced and has a solid, high quality feel.

The Senior topped the line up of the Duofold aerometric models until the introduction of the Maxima.  It is now very collectable and not at all easy to find in such good condition.
