In the 1930s, Conklin and Sheaffer each developed a piston filling mechanism that required just a single stroke piston with a gasket on it to create vacuum pressure to fill a pen's entire barrel with ink. It was a revolutionary design. Conklin called its pen the Conklin Nozac. Some of the pens were imprinted with an ingenious gimmick of a word gauge to show how many words were left in the pen before a refill. This limited edition recreation of that pen is a beautiful, oversized masterpiece. Tiny silver flecks look like stars in the night sky of this translucent blue and amber fountain pen. Numbered only 110 of 898, the word gauge purports to hold 7 million words per refill. We have not tested that gauge's accuracy, but we did test fill it with water and it works well. The insides are a little stained from past blue ink. You will write a smooth medium line with its 18k gold nib. Minimal wear. Complete with boxes and papers.
