Sheaffer Skripsert cartridge pen

Sheaffer Skripsert cartridge penThis is a cartridge pen from the early 1960s. Cartridges became popular in the 1950s and 1960s as ballpoints began to take over and inkwells were no longer provided in offices and schools. The pen is still in good working order but I do not use it. It belonged to my grandmother, Nellie Aaron Covington
