Model : Ink-Vue Ink-Vue Deluxe Green Ray Celluloid Fountain Pen, GT, Lever filled. Notes : The Ink-Vue employs a lever near the bottom of the pen which is unfolded and then pumped. Each stroke depresses a press-bar which in turn evacuates air from a diaphragm (aka bladder or sac), creating the vacuum needed for ink to be drawn into the barrel through a center filler tube.
