This is a Parker 51 Aerometric finished in Black with a Lustraloy Cap. It was made in the UK and is an excellent example of this very popular model from the early 1950's.
The pen is fitted with the reliable aerometric filling mechanism which has been fully serviced. It is fitted with a superb smooth Medium Oblique Italic 14ct gold nib and is in overall very good condition with minor wear marks commensurate with light use. The cap is in excellent order with minor wear marks and no dings.
