I need a replacement nib for a restoration project; an excess flick of the wrist fractured the existing nib during removal. The nib is marked "Parker | U.S.A." and is 26.5 mm (1.04") in length; I am not sure if it is technically a Demi or Standard nib (photo attached). The dimensions of the pen are as follows.
Overall length with cap and blind cap fully screwed in place: ~4 15/16"
Barrel diameter (widest point): 0.468"
Feed width: 0.200"
Any assistance would be much appreciated.
