i don't think there are any cb in europe! you should check out the next reptile expo in Hamm, Germany, if anybody in Europe breeds them or imports them that's the place where you could find em..good luck!
oh wait I found this user https://www.chameleonforums.com/members/happy14/ he's german and he opened a thread about his CB F. willsi a few yrs ago (he also has skype) give it a shot!
P.s I live in birghton too! it's cool to know that there are fellow cham keepers in the area!
