This is a Parker Duofold, the same model as the current production, but with a discontinued blue barrel. The size is Centennial. It's beautiful. Both the barrel and nib are in excellent condition. Everything is in good order. The outer box is from a black GT version, but I will include it. The only included accessory is one cartridge that came with the box.
