Bud unfortunately the use of the Agfa name/numbers cause confusion because they don't match the European/German Agfa formula numbers, so it's now best to refer to these old Agfa Ansco formulae as Ansco or Agfa-Ansco.

Gevaert were a separate Belgian company until they merged with Agfa in 1963, their products were also made in in Germany, France and Spain. In Gemany they operated as Voightlander-Gevaert, their products often being sold under the Voightlander brand name.

With Agfa it gets worse because Orwo continued making Agfa chemistry under the Agfa brand name until they were paid to drop it before Gevaert merged with Agfa. Later after re-unification Orwo split the chemistry division became Calbe.
