I have been trying to figure out why Geco (Gustav Genschow & Co) which existed, apparently, as a seperate entity from its founding in 1887, had its Durlach facility referred to in the German code list for companies as RWS and assigned code “dnh”. The RWS facility at Stadeln was assigned code “dnf”. RWS became a part of Dynamit Nobel in 1931, but it wasn’t until 1959 that Dynamit Nobel took over Geco as far as I can tell.
Below is the evolution as I have put together from a number of sources.
I suspect that, for some reason the Geco facility at Durlach was turned over to RWS to manage during WWII, but ownership remained with Geco. This is just a guess and I can find no documentation of this transfer or the reason for it, which may have been political.
Can someone shed light on this subject???

IG Farben was dissolved (“Entflechtung” in German). Out of this came a “new” DAG, now named “Dynamit Nobel”. This is a postwar name (except possibly in Austria). The sources which use “Dynamit Nobel” in the pre-1945 German context do not reflect the correct name, which was DAG. (JPeelen IAA Forum post 28409)
