This is a Parker 51 Vacumatic finished in Black with a Lustraloy cap. Made in the USA, this is a very good example of this model which dates from around 1944.
The pen is fitted with the reliable Vacumatic filling mechanism, borrowed from the earlier Vacumatic range of pens. It has been fully serviced and a new diaphragm has been fitted.
It is fitted with a wonderful smooth Medium nib and is in overall very good condition with light wear marks and scratches commensurate with use. The cap is in excellent condition with only very light scratches and no dings.
