This is a Parker 51 Aerometric finished in Dark Burgundy with a Rolled Gold Cap. It was made in the UK and is a good example of this very popular model from the mid sixties.
The pen is fitted with the reliable aerometric filling mechanism which has been fully serviced. It is fitted with a superb smooth Broad 14ct gold nib and is in overall good condition with light wear marks commensurate with use. The cap has some light marks but no dings.
