The Duofold Aerometric range was first introduced in the 1950's. The range consisted of the Slimfold, Junior, Demi, Standard, Senior and, the biggest of them all, the Maxima. They were all very well made pens and tremendously succesful. They all used the incredibly reliable Aerometric filling system.
This is a Standard Duofold and it is in good condition with some minor marks and scratches commensurate with use, it is finished in Classic Black with gold filled trim. The gold fill is worn in parts. It writes with a beautiful smooth Medium line and it uses the reliable aerometric filling system which has been fully serviced. It is ready to write.
