This is a Parker 51 Aerometric finished in Burgundy with a Rolled Silver 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 very good condition with only very light wear marks and scratches to the barrel and shell. The cap is ding free however the rolled silver finish shows light marks and scratches (it is rare to find a mint example of a rolled silver cap.)
