Thanks the yes it had "Color Umkehr Film" on the side so I looked up Umkehr and the translation was a little strange but I assumed it meant "reversal" , but thanks for the confirmation!

And sorry for the misunderstanding of ORWO I only just read that info on the link given at the top and I read a lot and probably misremembered the info.

Ok we've made some progress, I guess I'll read through that info and see if I can come up with some viable color developer.

OH does any of this film require a hardener?
