Nikon and Pentacon / Praktica

9 and 13 researched events on one shared scale. Nikon 1917–present, Pentacon / Praktica 1919–present.

The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
