This is a Parker 51 Aerometric finished in Teal Blue with a Lustraloy 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 smooth Fine side of Medium 14ct gold nib and is in overall very good condition with only minor wear marks commensurate with light use.
The Lustraloy cap is very clean with no scratches or dings.
