Tiger was completed with 2 3in/ 20cwt AA which she kept until 1923 when they were replaced by four 4in QF Mk V, by November 1924 two of these had been removed. In January 1925 she was rearmed with four 3in /20cwt AA Mk I. In March 1929 they were replaced by 4 4in Mk V. Two 2pdr Mk II pom-poms were present between March-September 1928
Good idea on the separate thread, my quoted info above from the other post was from Conway's 'All the World's Battleships' by Ian Sturton (ed.).
