This is a Conklin Nozac V-Line piston filler in Black in the larger size, c1937. The V-Line Nozac has a single color herringbone pattern in Royal Blue, Burgundy, Pearl, Black, and Nile Green. The V-Line has a fourteen facet plastic body with no Word Gauge, a plain single wide cap band and the Conklin clip. The black pens actually have the herringbone pattern, but it is sometimes hard to see except in the ink visible top section of the barrel. This pen is unrestored, so the pattern only shows under bright back lighting. The pattern alternates direction with each stripe. Large (wider) fountain pens sold for $7.50, slim fountain pens sold for $5.00, and matching twist action pencils were $3.50. Shorter Ladies pens were $5.00. This one is 5 1/4 inches long. Conklin offered 14 karat gold Cushon Point nibs with the Conklin Crescent logo or circle stamping with platinum plating in the circle. Nib grades offered were extra fine, fine, medium, coarse, stub medium, stub broad, left oblique, two way and Recorder in extra fine, fine and medium.
