Sempre relativo al [[1925]] viene riportata la creazione di un gruppo pennino intercambiabile, e la produzione di penne con parti in plastica realizzata con iniezione a stampo. Non vi sono documentazioni sicure di queste affermazioni ma in [[:File:1949-Mentmore-Plastic.jpg|una pubblicità]] del 1949 per una sussidiaria dedicata alla produzioni di parti in plastica ad iniezione si proclama una esperienza più che ventennale nel campo.

For some time the two brands were produced together; the [[Mentmore]] was transformed into a joint stock company in [[1930]]. The situation at that time is not clear, there are those who reported that the brand [[Mentmore]] has been progressively replaced by [[Platignum]], but by the late '30s to the' 50s, there is a large production of pens with this brand with explicit reference in advertisements to the ''"Mentmore Manufacturing Company"''. Also a patent of 1936 ({{Cite patent|GB|457212}}) explicitly shows the name of ''"Spot Pen Company"'' as the new name of '''Mentmore Manufacturing Company"''. However the ''"Spot Pen"'' name appears in an advertisement for the ''British Industries Fair'' of 1929, while maintaining the reference to the company as ''"Mentmore Manufacturing Company"''. Association with [[Platignum]] brand is established at least until 1951.<ref>thanks to [[:File:1951-Platignum.jpg|this advertisement]].</ref>

Around 1939-1941 (?) was produced the [[Mentmore Paramount]] model, an imitation of the [[Waterman]]'s [[Hundred Year]], it was also a plastic resin [[lever filler]] pen, and with a decorative transparent plastic bottom similar to that used by [[Waterman]]. The pen, however, had more slender lines. Another imitation is the [[Mentmore 46]], an hooded nib [[button filler]] pen, which was clearly inspired by the [[Parker 51]].
