The Parker 21 Super, introduced in 1956, differs from earlier models in that it has a 'new style' clip that was adopted for the Parker 45 in 1960. It also has an ink collector that acts as a second reservoir, as used in the Parker 51.
This pen is a most unusual colour, one that is not listed in the colour range for a '21', it is strikingly attractive, best described as 'turquoise'. This is the only example of a '21' that I've seen in this colour.
The pen has been fully serviced and tested, it is in excellent working condition. The bodywork has a showroom finish and the 'Lustralloy' cap, complete with a '21' engraving is similarly pristine.
The almost cylindrical 'Octanium' nib writes with a very smooth fine line, ideally suited to someone with a small 'hand' or for detailed work. The pen feels good in the hand and is a pleasure to use.
The Parker presentation box is in good, clean condition and is probably the original.
The Parker 21 super was a popular pen and sold in good numbers but it is extremely hard to find one in such outstanding condition, particularly in this very rare colour.
