The Agfa paper I bought in the 1960s and 1970s did not have grade numbers. They used these letters, in order of increasing contrast (example for Brovira, preceded by B)
BEW extra weak BW weak BS "special" BN normal--K I don't know what K stood for, contrast slightly higher than N, but maybe it was only in Portriga Rapid, not Brovira, so named PRK
BH hardBEH extra hard. This one, as many of you will remember, was exceptional and a lot of fun!

..................AGFA used a non-standard numbering system for their paper grades until about 1980, I don't remember the date. The numbers were one number _higher_ than Kodak numbers for the same contrast, that is, normal was AGFA No.3 and Kodak No.2. So AGFA Grade-6 was about the same as Kodak Grade-5, not an additional super contrasty grade..............................
