The Parker Vacumatic fountain pen was launched in 1933, displacing the Duofold as Parker's top-of-the-line product. The pen was originally named the Golden Arrow, a reference to the new arrow clip which would go on to become a Parker trademark, appearing in some form on almost all of Parker's subsequent pens.The Vacumatic featured a brand new filling mechanism—instead of the collapsible sac all Parker self-fillers up to that point had used, the Vacumatic featured a diaphragm that expanded into the barrel of the pen. Upon release of the diaphragm a vacuum was created, drawing ink into the barrel. Because the entire barrel could thus be filled, the Vacumatic boasted a much higher ink capacity than the Duofold it replaced.
