Sign *89 is not listed in Ventris & Chadwick's (1973) tables but it does appear in the appendix of Bennett (1964) as part of the Wingspread convention.
In recent times, CIPEM inherited the former authority of Bennett and the Wingspread Convention in deciding what signs are "confirmed" and how to officially represent the various sign categories.
