No problem, just sent it. There are three more relevant candidates for
subtags: pre-1911, 1911 reform in Portugal and the 1943 agreement
between Portugal and Brazil that Portugal implemented in 1945, but
Brasil only implemented in 1971, with the ammendment from 1971.

None of them are being currently used, so I'm not sure if I should do it
(I have really no particular interest in doing it). Suggestions?

Best regards,
