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'.  This Senior pen has a date code for 1956 stamped on the barrel.

The pen is finished in black with a Gold filled, chevron engraved cap band and Gold filled clip.  It is in excellent condition with a very good finish and the gold filling has held up very well.  The cap is a smooth screw fit, it tightens securely with one and a quarter turns and carries a black cap jewel.

The pen has been fully serviced and tested.  The aerometric filling system is easy to use and works well.  The large  14Ct. Gold No. 35 nib is a delight, it writes with a super smooth, broad line.  It would particularly suit someone who likes to write with a flourish.

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 a first year pen in such good condition.
