I changed the date from 1965 to 1950 The reference is a Japanese site I can t read and the only other hits on Google all appear to be wikipedia mirrors The date 1950 has at least been published whereas I got nothing for 1965 on GoogleBooks I was under the impression there were few bulls even over 55 57 ft in length by the mid 1960s let alone 60 feet A better reference needs to be found for the length and date though
