Hi, Dali - and the others;
about thirty years ago over here in Germany Agfa paper of course was very common particularly as Leonard - Hamburg was going to close down.
My brother and I bought many packages of the nowaday legendary Agfa Record Rapid, RR, a genuine baryta paper with a high amount of silver. Silver was missing in Argenta and Forte papers in the seventies and eighties. Thus Agfa Record Rapid was absolutely first choice.
Record RApid was slightly changing tone using e.g. Neutol neutral or Neutol WA (warmtone). - In my opinion Agfa Record Rapid was getting excellent in Kodak Selectol developer.
Today's "replacement": Honestly I am entirely fond of Ilford MG Warmtone baryta paper. Concerning the multi grading and also its behavior while developing, exposure time and developing time I think the Ilford MG WT is absolutely excellent.
Looking at my many 20x24" size enlargements I think that also Foma MG Classic 131 has a tone that is fairly close to the old Agfa RR paper, depending on what developer you use. - In general I prefer Kodak Dektol, a rather cool developer giving the warmtone papers a kind of marble tone. For the Ilford MG warmtone I also used the Ilford BRomphen, which also give great tone!
Concerning the Cadmium: Yes! As what I know Cadmium was used against any kind of oxydation. Thus: If you rather buy very old paper, up to the mid-seventies, you are right off; do not buy the ninties-Agfa papers as they turn grey as soon as you put them into the developer bath. - Thus: If you buy any Agfa Record Rapid, rather go on the old oval labelled packages.
Wishing you all the best and much fun! - With greetings from Lake of Constance.
