This is a Parker 51 Aerometric Double Set finished in Grey with Lustralloy caps. The set was made in the UK around 1959 and is a very nice example of this desirable model.
The pen is fitted with the reliable aerometric filling mechanism which has been fully serviced. It is fitted with a lovely smooth Extra Fine nib and both pen and pencil are in very good condition with light wear marks and scratches commensurate with use. There are no dings in either cap. The set is presented in its original box.
