This is a superb example of this early Swan Self Filling Fountain Pen, this is the 172/53 which was made in the UK and dates from around 1927. It is a small pen, almost certainly a Ladies pen, with a chatelaine ring instead of a clip.
The pen is finished in the rare and wonderful Orange marble with a gold filled tassie ring, lever and cap band. The imprint on the barrel end shows "172/53" The pen is in excellent condition with no chips or cracks. The colours are clear and deep and the pen is in fabulous condition apart from a little pitting to the lever.
The No.2 Medium Flex nib writes smoothly and gives a lovely shape to your writing. The pen has been fully serviced and is ready to write.
