Ihagee and Schneider-Kreuznach

13 and 5 researched events on one shared scale. Ihagee 1912–present, Schneider-Kreuznach 1913–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.
