This is a nice clean example of the classic Parker Duofold AF button filler. AF means it has the later Aluminium button which replaced the original brass button. It was made in the UK around 1940. It is finished in classic black with gold filled trim to the clip and cap ring.
The pen is in very good condition with minor marks and scratches commensurate with use. The gold plating is in good order with only light wear.
The pen is totally original and has been fully serviced.
The nib is a lovely Medium which writes smoothly. These are lovely pens and quite scarce in good condition.
