I am reposting as I can no longer edit my previous post to emend some details. I am looking for a replacement 14k single-tone nib for a Vacumatic Major (final style), medium or fine point. The original nib fractured during disassembly of the pen and is marked "Parker USA" and is 26.5 mm (1.04") long. The width of the feed is 0.200". The broken original nib is pictured below; I'd be looking for something substantially the same.
Any assistance would be most appreciated.
