I wonder if any of their films were ever made available for amateur use on 9.5mm film. the Pathé Baby amateur film system for home use were available as early as 1922, these were fairly cheap hand cranked projectors, later ones had an electric motor along with a transformer to lower the voltage down to less than 6v
I have several old 1930 era 9.5mm projectors and piles of old film from another interest of mine dating back to the 1960's
