Filling systems

It was introduced by Parker in 1948, as a new filling system adopted on the 51 in place of the previous vacumatic. Actually for the operating modes this system is very similar to the sleeve filler used by LeBoeuf, because it is based on the pressure of a rubber sac to be made by a side opening on the metal cylinder that contains the same, which is accessed by unscrewing the pen body from the nib section.
