Table schema:
CREATE TABLE table_name_42 (owner VARCHAR, re_entered_service__p_ VARCHAR, pre_conversion VARCHAR)

Question: Who owns the item that was a T326 before conversion and re-entered service on 11 September 1985?
SQL: SELECT owner FROM table_name_42 WHERE re_entered_service__p_ = "11 september 1985" AND pre_conversion = "t326"
