This is a wonderful Parker 51 Aerometric finished in Black with a Rolled Gold cap. Made in the USA, this is a very good example of this model which dates from around 1955.
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 excellent condition with only very light wear marks and scratches commensurate with light use. The cap has no plating wear and is in very good condition with no dings.
