Waterman introduced its first lever fillers in 1915 and they soon became market leaders.

The "standard" size 52 was meant to fit almost every hand. Waterman was anyway able to offer a wide range of variations in size (and later on in color, too) to fit large hands (sizes went from 51 up to 58) offering shorter (indicated by "V") and thinner versions of the same model ( indicated by 1/2).

This Waterman 55 is a perfect size for  a male medium-sized hand. 

The pen is in excellent condition and it is fitted with a very responsive, smooth and flexible nr. 5 Waterman nib.

The one is in excellent condition apart from a tiny damage on the side of the cap above the cap band (see picture)
