The AF or "Aluminium Filler" Duofold was made by the UK arm of Parker from 1948. A very short production run that means these pens are not common today. It is the immediate predecessor of the much more common Aerometric Duofold and looks outwardly almost identical. This is a glossy jet black example that is in very good condition. The only damage I can see on this pen is some very minor discolouration to the plating a the very edges of the pocket clip and the cap band. You will not even be able to notice this without using magnification. The cap has a black conical end "jewel" and a rolled gold Parker Arrow pocket clip. There is also a wide cap band - also rolled gold - that has the usual "deco" engraving. At the end of the barrel is a blind cap. This can be unscrewed and beneath is the original aluminium filling button and aluminium collar that it is held in. The barrel imprint is lovely and deep and crisp on this pen. The lovely large nib is in 14 carat yellow gold in medium point, marked "PARKER DUOFOLD" and "14K PEN" with "N" for Newhaven.
I have fully serviced this pen. It fills and writes superbly. The nib lays down a very smooth fine width line that is both wet and consistent.
