The Parker 51 Custom, this set, differed from the 51 Classic in that it has a 1/10 rolled Gold cap whilst the Classic cap is 'Lustralloy'.

This set comprises a fountain pen and matching pencil.  The pencil is a 'continuous feed' mechanism which operates by depressing the cap to release the lead.  I have not attempted to remove the cap as the pencil is working well and new leads are fitted through the nozzle. The pencil is in excellent condition, the cap is ding free and the barrel has a first class finish with a clear imprint.  The grooves on the cone are gold infilled, consistent with a Custom pencil.

The set is in superb condition, it has a pristine shine and the Gold filled caps are ding free with an excellent surface. 

The pen has a 1955 date code and the pencil is dated for the first quarter of 1956, this is not at all unusual as sets were assembled as they were dispatched from the factory.

The pen has been fully serviced and tested.  The aerometric filling system fills well and the 14 Ct. Gold nib is a gem.  It writes with a super smooth, broad line, the hooded design precludes any flex in the  51 but Parker managed to give the nib a very pleasing 'soft' feel.

The Parker ' mock croc'presentation case, correct for the set, is in sound condition.  The satin lined interior has one age mark and light pencil marks where the pencil has been put away with the lead extended. It does show, however, that the set has been used with care and returned to the box after use.

The Parker 51 is the most successful pen ever made and has a great deal of prestige.  It is the first choice of many pen enthusiasts as a daily writer, a testament to it's reliability and iconic status.  A complete, all correct set in such remarkable condition is a highly collectable item but would also serve well as a practical vintage writer.
