@gorbas - thanks. Would love a copy of the whole book :-) so not practical - but as mentioned, if anyone reading this knows of one for sale, I would be interested!
Calbe offer some CD-standard developing agent as raw chemical, but not CD-1. That may mean, they don't use it in A49, don't make A49 any longer, or keep it for themselves.
Make your decision.
