This is a Parker 51 Aerometric finished in Burgundy with a Lustraloy Cap. It was made in the UK and is an excellent example of this very popular model from the early to mid 60's.
The pen is fitted with the reliable aerometric filling mechanism which has been fully serviced. It is fitted with a superb smooth Fine side of Medium 14ct gold nib and is in overall very good condition with minor wear marks commensurate with light use. The cap has light marks but no dings or dents.
