Around 1936,[1] following another innovation made by Sheaffer after Vacumatic launch, were also introduced new Doric models with transparent body and new filling system (called plunger filler), the same filling system was adopted even for some economic models, similar to the Doric but produced in round smooth celluloid. In the late 30's, despite the introduction of other economic models such as Pacemaker and Air-lite the Wahl Eversharp was constantly losing market share.
