This is a Warwick lever fill fountain pen, a different knock-off of the late 1940s Waterman Taperite Citation, probably made in the late 1940s or early 1950s. The cap is two pieces, with a gold plated ribbed metal bottom section and an injection molded cap top. The gold plated clip attaches with a top rivet through a cap top washer. The nib, unlike Waterman nibs, is very firm, and likely gold plated stainless steel. The 5 1/4 inch long pen is made of injection molded plastic and came in burgundy, blue, green and black. This pen was obtained with large number of new old stock Wearever pens and may have been made by David Kahn, Inc. It was sold with a matching pencil in an unmarked paperboard box with no instructions. They likely sold for $1 or less.
