The Parker 51 Aerometric, first made in 1948, promoted Parker 'Superchrome' ink on the filler sleeve. This reference was removed in 1957, slightly before a 'halo' was added to the cap. The lack of a halo or Superchrome reference dates this English made pen to 1958.
The pen is in exceptional condition throughout. It has been thoroughly cleaned, serviced, and tested. Finished in gleaming, unmarked classic black, it has a ding free lustralloy cap with a Chrome 'arrow' clip and a pearl end stud. The barrel end is clearly inscribed 'Parker. made in England', it is a crisp and clear imprint.
The filling system works perfectly and takes up a good volume of ink. The design of the hooded section precludes any flexibility in the nib but Parker still managed to give the 51 nibs a very pleasing 'soft' feel. This example writes with a super smooth, medium line.
The Parker 51 has been described as 'the best pen Parker ever made' and this example certainly supports that claim, it would make a first class, and most prestigious, every day writer.
