For some time the two brands were produced together, the Mentmore was transformed into a joint stock company in 1930. It is not clear the situation at that time, there are those who reported that the Mentmore brand has been progressively replaced by Platignum, but by the late '30s to the '50s, there is still a large production of pens with this brand. Association with Mentmore is established at least until 1951.
