The Parker Duofold Standard , along with the smaller Demi version, was the first Aerometric Duofold to be made in the Newhaven factory,1953. 

The pen is in excellent condition, it has a bright surface, with a clear imprint. The  Gold filling to the clip and decorated cap band is pristine.  The clip is secured by a colour coded 'jewel'.

The original, correct, No. 25 14Ct. Gold nib is straight and well aligned.  It  writes with a  medium line, and has the very pleasing 'soft' feel often associated with these pens..  It is a very comfortable and 'easy' writer.

At 13.2 cm. capped and 14.7 cm. posted the Duofold is an average sized pen in terms of length but is a good deal wider than most, giving it a very solid, chunky feel. 

The presentation box is brand new, it will serve well for transportation, protection, and display.

The Parker Aerometric Duofolds of the 1950s were excellent writing instruments which sold very well, despite the competition from the ballpoint.  Parker probably under-priced the pen in order to resist the pressure.  Sixty odd years later the pen is still outstanding value, particularly when compared with a new Gold nibbed pen of similar quality.  It would make a very good vintage daily writer.
