This is an excellent example of the Parker 61 Heirloom. The top of the range Heirloom pens sported a rainbow cap made from alternate layers of different colurs of gold. The effect is very striking and the pens are much less common than the standard Classic and Custom pens. The Heirloom caps were discontinued in 1968 due to high production costs and high reject rates.
The pen has been used very lightly and is in very good condition with only very minor marks, there are no dings in the cap. It uses standard Parker cartridges or an optional converter can be fitted to enable it to use ink from a bottle. It is fitted with a lovely smooth Medium nib.
