This is a Conklin Nozac 5M Word Gauge Green Pearl piston filler fountain pen c. 1935.  This 5 1/8 inch long model has a ten faceted cap and barrel with a clear ink view upper barrel.  The two barrel pieces are threaded and sealed together.  It was also available in Jet Black and marbled Red Pearl and sold for $5.00.   The markings on the ink view window indicated how many thousands of words of ink was left in the pen.  The pen features a two-tone plated version of the circle stamped Toledo 14 karat gold nib.  The pen has the 1918 patent clip.  The inlaid crescent appears above the pocket clip.  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. 

This is a Conklin Nozac 5000 word Chevron design in green celluloid c. 1936.  Conklin introduced two new lines, Chevron and Penline in September 1936.  Each is constructed of tubes made from sheet celluloid with repeating striped patterns.  Chevron pens have translucent strips separated with strips of alternating direction rows of colored celluloid arrows.  The sheets were wrapped into cap and barrel tubes that were then worked into finished caps and barrels.  The seam can be found with careful examination.  Look for the white line near the base of the cap.  This tube construction method allowed the barrel to be a single piece with the translucent strips in the top half for viewing the ink level.  You can see the Word Gauge on the top left of the barrel and the imprint further down.  The bottom half hides the piston mechanism.  The Chevron came in three colors:  red and silver, silver and green, and two sizes, 7000 word and the slimmer 5000 word shown here.  Both pens are the same length, about 5 1/4 inches long.  This example has the 14 karat gold Conklin Toledo nib instead of the Cushon Point nib that was introduced in 1936.  The model also features the new 1936 patent clip.  The 7000 Word Gauge Chevron sold for $7.50 and the 5000 sold for $5.00.  Matching pencils were $3.75.

This is a standard size Conklin Nozac Penline Green Pearl faceted piston fill fountain pen c. 1936. This size pen has a 12 facet cap and barrel. The Nozac Penline was introduced in 1936 and came in rounded and faceted versions. Nozac pens use a piston filling system Conklin introduced in 1931. The pen fills by twisting the end cap while the nib is in ink. The ink level could be seen in the translucent barrel. These 5 3/16 inches long pens were offered three colors, including Grey Pearl, Red Pearl, and Green Pearl with the new 1936 patented clip. This example has the 14 karat gold nib stamped CONKLIN over CUSHON over POINT over 14KT over U.S.A. At the top of the nib is the Conklin Crescent logo. This pen also has a black section. Standard size Nozac Penline pens like this one sold for $5.00 and the matching pencil was $3.50.
