Some of your research is not correct. For example, the Soviets left the Orwo plant intact in Wolfen, just using some ideas and spare equipment in their own plants.
The Agfa method was used by the Japanese before and during the war at both the Fuji and Konica plants. It was given in an exchange program just before the war.
After the war, the Agfa formulas were published in the BIOS (British) and FIAT (US) intelligence reports. Each have significant errors in translation and also errors of omission. This was in 1945. Before that, Kodak produced two color films themselves that were contemporary with the German films.
Ansco AGFA used Agfa chemistry and was nationalized by the US government at the start of the US effort in WWII. The formulas used by Ansco were about 1 generation behind the Agfa products. After Ansco reverted to private ownership, they continued to evolve their products towards the Kodak type until the company failed.
Kodak color processes used dye forming chemicals that were terminated with "fatty" tails and which were dissolved in oils in the coating. Agfa and all other products contained dye forming chemicals that terminated with sulfonic acid groups. These groups affected the viscosity of gelatin and therefore had to be coated one layer at a time. The Kodak dye forming materials did not affect viscosity and thus Kodak was able to develop the slide hopper which allowed up to 14 layers to be coated at one time.
Agfa used several processes from the start and these evolved as their products evolved. They had at least 3 for color neg and 3 for color paper before they moved to the Kodak fat tail image formers which allowed them to coat multiple layers at one time. Thus they could speed up operations and keep up with Kodak in production.
Agfa used gold + sulfur sensitization but this was under development by Kodak in an independent effort before the war. The captured documents revealed the Agfa method, and Kodak went on to develop a superior method with better keeping. The original keeping method involved the Agfa method of a sulfur restrainer that was later replaced by Tetra Azza Indene. This is now commonly used throughout the industry, but with improvements in the method of addition and the combinations of chemicals used.
Near the end of the life of Agfa, tests on image stability and raw stock keeping of their products proved them to be inferior to both Kodak and Fuji. Their grain and color reproduction were similar.
I have much much more on this. I must say though that the Agfa Brovira formulas in Glafkides and reproduced here on APUG have several glaring errors and omissions.
