However, just as this OP article pointed out, it says "admitted to registry" - not necessarily "fully recognized". Breeds are put on the "Miscellaneous" list and get ILP numbers for registry purposes, until the BC establishes a solid stud record for some generations (and they wish to be fully recognized). So, as far as I can tell, the B&T may simply have been put on the "Misc" grouping.
