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 Blue with a Gold filled, chevron engraved cap band and 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. The original 'pli-glass- ink sac has darkened with age but is unstained and still retains some transparency. 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 has a broad stub point, it writes with a smooth, broad line. The horizontal strokes are finer than the verticals, giving line width variation to add character to the writing. It would suit someone who enjoys writing 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 in such good condition.
