This is a new shot of the Conklin All American Sac-less Vacuum Pen in Reptilian Gold Green Vein c1936. This 5 3/16 inch long model also came in Reptilian Pearl Gray and Reptilian Foliage Red Vein and sold for $2.95 with a $1.00 matching twist action pencil. The clip has the Conklin Crescent at the top and is stamped with its patent number. The standard gold nib is plain and stamped simply ALL AMERICAN, with no hallmark. The barrel has translucent areas that are very ambered if you look closely. Unlike the Quick Fill pens, the plunger is accessed by removing the end cap instead of the end cap itself being the plunger handle. The barrel imprint, not shown, reads THE ALL AMERICAN PEN over MADE IN U.S.A. over A CONKLIN PRODUCT. These streamline All American pens have two imprints, slightly different.
