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.
The pen is finished in Red with a Gold filled, chevron engraved cap band and Gold filled clip. It is in excellent condition with just light usage marks, it has a very good finish and the gold filling has held up very well, as has the barrel imprint. The cap is a smooth screw fit, it tightens securely with two 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 writes with a smooth, fine line and has a slightly 'soft' action. It writes with virtually no pressure and is a very comfortable and 'easy' writer.
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 Parker box, used until around 1956, has a 'doodle' but is probably original so should be kept with the pen.
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.
