Moore was one of the early fountain pen manufacturers, a major player in the early years, then less so as the “Big 4” dominated after the late 1920s. Even as a progressively lesser brand, Moore pens were successful from the early 1900s until the 1940s. They pioneered some designs in safety pens, and their hard rubber pens were very nice; later celluloid models were too often quite pedestrian. Unable to do more than follow industry trends and keep up with the leaders, Moore always produced good quality but faded as a brand. Moore's post-WWII Fingertip model was truly creative, but too late. Moore survived until the late 1950s.
