In [[1935]], the company invented a telescopic [[piston filler]] (patent {{Cite patent|AT|149872}})  with two concentric sections which allowed to have a much shorter mechanism, resulting in more space for the ink reservoir. The mechanism was mounted on a model called [[Luxor Teleskop| Teleskop]], and it seems that it is the same one that was later adopted also by [[Montblanc]] for its flagship models of the series [[Montblanc 13x|130]] and [[Montblanc 14x|140]].
