The Parker Duofold Senior aerometric filler was only produced from 1954 until 1958, a relatively sort production run, always good for collectors. As date code stamping on the barrel ended in 1956 and this pen doesn't have one, it can be dated from 1957 or 1958.
The pen is finished in classic black with a Gold filled, chevron engraved cap band and Gold filled clip. It is in excellent condition with only light usage marks. 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 correct 14Ct. Gold No. 35 nib is larger than the standard Duofold nib and writes with a smooth, medium line and is a very comfortable and 'easy' writer.
The pen is presented in a contemporary Parker box along with the instruction leaflet, probably the original. It has a light sqiggle on the lid but is in very good clean, sound condition.
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 excellent condition.
