These are photos from when I first took delivery of my Nakaya, an aka tamenuri (red urushi lacquer) Neo-Standard, from back in 2016. The nib was an SF with added flex cuts, and though it ran dry fairly quick, when it was primed it wrote in an almost brush-like manner. It was very unique, but difficult to use every day, which is part of why I got rid of it.
Beautiful pen! Sorry to hear it didn’t work for you.
