For this reason in 1927 was created a second version of the filling system, in which the outer barrel was anchored conventionally to the nib assembly, and in its place was used to generate depression a second metal tube placed between it and the inner barrel. The depression system was anchored to the bottom of the pen which was a blind cap, in this way it was sufficient to unscrew the bottom of the pen to perform the loading, which at this point could be performed with one hand.
