I'm not actually sure if this is the last use but it's the latest I've heard of and think it's kind of neat Anyone know of later? I knew that some Lights were converted to anti-aircraft use and they were used in the desert as late as 1942, such as this photograph from the IWM: THE BRITISH ARMY IN NORTH AFRICA 1942. © IWM (E 16827) IWM Non Commercial License However, from this document I photographed today about operations in Tunisia, April 12 1943 -- LIGHT TANK MK VI ANTI-AIRCRAFT A few of these vehicles are held by both 25 Army Tank Bde and 26 Armoured Brigade. They are well liked by the users, although 26 Armd Bde state that the mechanical condition of their vehicles is so poor as to make it necessary to limit the amount of running carried out. As far as the armament is concerned, the 25 Army Tank Bde found it was necessary to adjust the firing bar to ensure that all four guns fired simultaneously while 26 Armd Bde report that their only trouble has been due to faulty feed at high angles of elevation caused by the angle of the belt when the guns are in that position.
