Curiously Michael Smith in his book 'The Emperor's Codes: The Breaking of Japan's Secret Ciphers' refers to two RAF units, 357 WU and 370 WU, were attached to Royal Navy codebreaking centre in Ceylon, HMS Anderson, although the two RAF units were known as RAF Anderson. See pg. 233. Via Google Books. In May 2021 this website appeared, it does refer to HMS Anderson - although it is based on another's work cited in Post 10: RAF STATIONS IN SRI LANKA DURING WORLD WAR II & AFTER
