This is a nice example of the Duofold Senior which was made in the UK around 1940.
The pen is finished in the rare and beautiful blue-green marble. The colours are still bright and vibrant with none of the usual discolouration common with these pens. The imprint on the barrel is a clear and legible. There are some minor marks and scratches to the cap and barrel and the gold plating is showing signs of wear. A small crack to the top of the barrel has been sealed and repaired (See photo). The pen is totally original and has been fully serviced.
The nib is a lovely medium which writes beautifully. These are lovely pens and the colouring on this one is exquisite.
