Thanks for the suggestion.
There are several reasons for the name CHS 100 II (beside the technical description):
1. The market exit of Fotokemika in 2012 came quite surprising at that time. Resulting in loosing our manufacturing source of the ADOX CHS line of films. We had to react as fast as possible, because lots of loyal CHS customers wanted a solution for their future needs. And the spectral sensitivity of the CHS films was the unique characteristic of the CHS 50 and 100 which was liked by our customers most. Therefore our intention was to design a successor for CHS 50 and 100 (CHS 100 II works excellently at EI 50/18° as well) with the same spectral sensitivity, but significant improvements in detail rendition (sharpness, resolution, grain, shape of the characteristic curve) and in production quality / QC (Made in Germany).
The name CHS 100 II was intended as a clear signal to our CHS 50 and 100 customers that we have a solution for their needs.
2. The CHS 100 II was not intended to be "the only one medium speed BW ADOX film forever" from ADOX. There are more options and plans for the long-term future. Including using different technology. And therefore also some potential product names were / are not "free" or possible for the new CHS-type film.
The name CHS 100 II for this film is meanwhile very well established for many years. Changing the film name now after all these years would lead to lots of confusion in the market and under customers, and to significant additional costs for ADOX. All that would be counterproductive for the future success of this product. It would have negative impacts on both our customers and our company.

Thank you for taking the time to reply! Yes, it would cause some confusion, like the Adonal vs. Rodinal one, and probably add to the confusion over "rebadged films". Some get the feeling that rebadging/renaming makes that product "inferior", even though the products are the same. Adox CHS 100 II is one of the best films on the market. Better quality and replaces both the old CHS/Efke 100 and 50 in terms of grain and spectral sensitivity.
