This is an Eagle Epenco black and cream lever-fill fountain pen c. 1933-1936. The celluloid cap and barrel is an unusual series of bands of solid black panels and black and cream striped panels wrapped in a spiral around the cap and barrel. The striped panels bleed into the black panels for an interesting effect. The 5 inch long pen uses a patented clip that appears on pens in the 1932 and 1937 catalogs, helping date the pen. By 1937, this clip design is found primarily on lower end models. It has no barrel imprint, so the indications it's an Epenco model is the clip and the gold plated stainless steel nib, marked EPENCO over N.Y. Epenco was the low cost brand of the Eagle Pencil Company and such fountain pens sold for 50 and 25 cents in 1937.
