That picture was taken in February 1943 according to this written on the back.
20 February,1943 to be exact.
This next picture was shared in August 2014 by Cathy, Gil Gillis’ daughter.
I just added a yellow circle to F/O Snider.
Gil Gillis is in the red circle.
I took the following information on Wikipedia to get a clearer picture.
World War II
On 16 May 1940, No 238 reformed at Tangmere as a fighter squadron with Spitfires but in June these were replaced by Hurricanes. It became operational on 2 July and spent the period of the Battle of Britain in the Middle Wallop sector, apart from four weeks in Cornwall.
In May 1940, No.238 reformed at Tangmere as a fighter squadron with Spitfires but in June these were replaced with Hurricanes. It became operational on 2 July and spent the period of the Battle of Britain in the Middle Wallop sector, apart from four weeks in Cornwall. In May 1941 the squadron left for the Middle East its aircraft being flown off HMS ‘Victorious’ to Malta while the ground echelon sailed round the Cape of Good Hope. After refuelling in Malta the Hurricanes flew on to the Western Desert where they were attached to No. 274 Squadron, pending the arrival of the squadron’s own ground crews. By the end of July, No. 238 was again operating as a complete unit, flying escort missions and fighter patrols throughout the campaign in the desert until after the battle of El Alamein. It was then withdrawn to Egypt for air defence duties and converted to Spitfires in September 1943. In March 1944, the squadron moved to Corsica for sweeps over northern Italy and in August covered the Allied landings in southern France. After moving there for two months, it was withdrawn to Naples and disbanded on 31 October 1944.
On 1 December 1944, No. 238 reformed at Merryfield as a transport squadron and was originally intended to fly Albemaries. In January 1945 it received Dakotas and on 14 February its first wave of ten aircraft left for India where they began supply-dropping and casualty evacuation missions over Burma. In June the squadron moved to Australia to provide transport support for the British Pacific Fleet as part of No. 300 Group, officially disbanding there on 27 December 1945.
