This is an excellent example of an early Swan Self Filling Fountain Pen, this is the 130B/61 which was made in the UK and dates from around 1930.
The pen is made from Mottled Red hard rubber in the Woodgrain pattern with two gold filled rings on the barrel and one on the top of the cap. The imprint on the barrel is clear and legible and the pen is in excellent condition overall with some very minor marks.
The Medium nib writes smoothly and has a lovely light flex to it.
The pen has been fully serviced and is ready to write.
