The Parker 51 'Aerometric filler' version was introduced in 1948. This example is finished in 'English Burgundy', referred to in the U.S.A. as 'Blood Red', or 'Bloody Burgundy' as the American Burgundy is very close to brown. This pen is much 'redder'.
Parker introduced a 'finger clutch to the cap in 1962 and removed the cap lip in 1964. As this pen has the new clutch and still has the cap lip, it can be fairly accurately dated to 1963.
The pen has a deep lustrous and unmarked 'showroom' finish, and a ding free 'Lustralloy' cap with chromed 'arrow' clip, and pearl coloured cap stud. It has been fully serviced and tested and is in first class working order. A full service is recommended for a 51 as the very fine fins that form the ink collector are often blocked with dried ink residue, reducing the efficiency of the system.
The pen is an exceptionally good writer, with the lightest of touches it produces a beautifully smooth and consistent medium line. Whilst the hooded nib design precludes any flex in the 51, Parker managed to achieve a very pleasing 'soft' feel with their 14 Ct Gold 51 nibs, this one is a pleasure to use.
The box is new, it is of high quality and will serve well for transport, protection, and display.
The Parker 51 was ahead of it's time in many ways, so much so that it was first advertised as 'like a pen from outer space', it went on to be the most successful fountain pen ever made. Eighty years, or so, later it has been resurrected as the 'Parker 51 reimagined' but I'm afraid the new pen does not match up to the original and certainly doesn't have the same amount of prestige.
