I have formulae for Agfa Lupex, Brovira, Portriga, Momento, Roentgen,
Copex, and other stuff made at Leverkusen plant, from
July-August 1945. All Brovira formulae I looked closely (Brovira
extrahart, hart, normal, spezial, weich, extrahart-braun, hart-braun,
normal-braun, spezial-braun, weich-braun) contain chloride, iodide or
both in addition to bromide. I don't know if later Brovira was pure
bromide but I don't think it's very likely.
