This is a Parker 51 Aerometric finished in Burgundy with a Rolled Gold cap. Made in the UK, this is a very good example of this model which dates from around 1960.
The pen is fitted with the reliable aerometric filling mechanism which has been fully serviced. It is fitted with a lovely smooth Broad Oblique Italic nib and is in overall excellent condition with only very light wear marks and scratches commensurate with light use. The cap is ding free and the pen is supplied in its original box.
