Translations:Chilton/8/en

The mechanism was simple, functional and robust, and allowed Chilton pens to use ink sacs with significantly larger dimensions than those of competitors, so that the pens were promoted with the slogan Twice the ink. However the shape of pens was not proportionate because to block on the sliding barrel the cap had to be extended over the full length of the nib section, and that should be quite long because it was used to hold the pen when filling it. So the pens were having quite an excessive cap length.
