Magnet and Mammoth were both children's offshoots of Methuen -- I have a feeling one was specifically for comics, but I'm not sure. Neither exists now.
Interestingly, inside one of the older books it says Mandarin is an offshoot of the Octopus publishing group. Mandarin and Octopus are not mentioned anywhere else, so the statement seems a little inconsequent.
All the Tintin books I or my family own are published by Mammoth, except for: Mr. Pump's Legacy which is Magnet, a 3-in-1 (The Broken Ear, The Black Island, and King Ottokar's Sceptre) which is Methuen's Children's Books, and another 3-in-1 (The Castafiore Emerald, Flight 714, and Picaros) which is Little, Brown and Co.
Oh, and my brand spanking new English copy of Congo (thanks to my brother for the birthday present!) is Casterman.
