Was this batch of R09 made by Connect Chemicals Production & Services in Vaihingen/Enz?

This, along with all other RO9 one shot/adox versions of Rodinal is made by Agfa and re packaged for the seller. It is rodinal in all respects bar the name, sp use Rodinal times/instructions.
And do remember that time and instructions should be considered starting points rather than unbreakable laws. When using R09 I'm usually overexposing by 2/3 of a stop and underdevelop by 15-20% of the recommended time. Works for me.
So, no matter where it comes from (Calbe or Vaihingen/Enz) it is reddish and not yellowish as the Agfa Rodinal from the 90s? Does the color simply change from re-bottling and re-packaging or is there a more subtler, chemical difference? I am asking all of this in order to choose the best developer with original APX 100 in 120 format intended for sharpest possible 45x45" RC prints.
No Calbe's version is an older formulation as Calbe were once part of Orwo. RO9 was the Agfa forlual number Recepte 09, R10 is also a p-Amininophenol based developer.
My head hurts, so much confusion. Old formula, original formula, but not the same. ???? :(
