Can you please define and explain the different (and differences of) hashkofos between 1) BMG 2) Chaim Berlin and 3) Chofetz Chaim (as apparently these are the only three surviving Litvish hashkofos, if I understood the point)?
Presumably the above point excludes the Litvish yeshivos in Eretz Yisroel, which still have their unique prewar hashkofos. Do yeshivos like Mir in NY (or Torah Vodaas) not have non-BMG hashkofos?
