In realtà il ''"[[Lucky Curve]]"'' era semplicemente un buon alimentatore, che rimase in produzione fino al 1928, e venne usato come marchio di fabbrica per numerose penne; ma ci sono forti dubbi che la forma curva abbia davvero un qualche effetto particolare nell'evitare gli accumuli di inchiostro, tanto che numerosi riparatori la tagliavano, in quanto rendeva difficoltoso il reinserimento del pennino e dell'alimentatore nella sezione.
