In 1936 was introduced and patented a new model, the [[Lucens]], with an original (for Italy), loading system, called ''[[stantuffo tuffante]]''.<ref>meaning ''diving piston''.</ref> The mechanism is essentially identical to the one used by [[Dunn]] about 15 years earlier, although it is not possible to determine whether it was a copy or an original independent creation. Despite this the [[Lucens]] is one of the most beautiful pens ever made, especially for the beauty of the different kind of semi-transparent celluloid used to made it, giving a direct view of the ink level.
