Around [[1925]] [[Mentmore]] introduced the ''Platignum'' brand for its lower-end pens production. At that time it seems there was some sort of reorganization of the company and that the intention was to use the ''Platinum'' name, but this was not registrable as a trademark since it's the name of a metal. Therefore, the name was slightly changed and the ''Platignum Pen Company'' (it is not clear how much independent from the parent one) was specifically created, and it began directly marketing ''Platignum'' branded pens, focusing on the low-end production compared to pens distributed by the main brand.
