The Parker Duofold NS, for 'new style', was introduced in 1946 and replaced around a year later by the Duofold AF, the 'aluminium filler'.  

The pen is a traditional button filler, unchanged from the original Duofolds, but it is a 'twin jewelled' pen, it has a Gold filled tassie and colour matched stud at the end of the blind cap.  At 13.7 cm. capped and a very impressive 16.3 cm. when posted for use it is signifcantly larger than the 'standard' U.K. Duofold.

The pen has been restored and is in excellent condition throughout.  It is an unusual Chocolate Brown colour with a good finish and a clear barrel imprint.  the gold filling to the clip, tassies, and decorated cap band is also in good order.

The nib is stamped:

'Parker. Duofold. 14K. Pen. N.'

The 'N' signifies that the pen was made in the Parker factory at Newhaven, later pens carried a number but not the 'N'.  It is curious that the English branch of Parker use '14K', rather than '14Ct.' for the Gold content of the nib, 'karat' is the American spelling, the  English use 'carat'.

Duofold nibs vary in the degree, or lack of flexibility, this one is unusual in that it has a full flex, giving good line width variation and allowing character to be added to the writing.  My scrawl does not do the nib justice but anyone with a decent 'hand' would enjoy producing impressive results.

This is a fine example of a Duofold NS.  The unusual colour and flex nib combination is not easy to find, particularly in such good condition, at 77 years old it is very collectable but would also make a first rate, every day vintage writer.
