I am in the process of researching dad.s postings in the Middle East , 1941-1944 .His name is Eric Martin Winter and worked with 53 RSU, 51RSU, 103MU, 111MU, and others in Egypt, Libya and UK. I have many photos of his time there. Some other letters and numbers that I’m not sure of are; 3064 SE, 6456 SE, and 11 PDRC any info on these would be greatly appreciated.
PDRC is Personnel Dispatch and Reception Centre (Royal Australian Air Force) from: PDRC and more on: RAFCommands Archive :: PDRC There are several choices here for RUS: RSU and too many for SE: SE
In the context of someone serving in the RAF in the period I would suggest that the various units are:- 53 Repair & Salvage Unit which had several incarnations between Oct 1940 and Oct 1944 around the Med 51 Repair & Salvage Unit formed 6/40 in Egypt and disbanded 11/44 in Italy The MUs are Maintenance Units in Egypt 3064 SE would be 3064 Servicing Echelon between 14/11/41 and 22/3/44 when it was redesignated 6456 Servicing Echelon. These units were responsible for servicing Beaufighter and then Mosquito nightfighters of 456 (RAAF) sqn at various bases until disbanded with the squadron on 15/6/45.
Maybe a wander through the TNA files of Kew Example : 53 Repair and Salvage Unit; formed at Aboukir (Egypt) and later moved to Athens (Greece)... | The National Archives Reference: AIR 29/803/3 Description: 53 Repair and Salvage Unit; formed at Aboukir (Egypt) and later moved to Athens (Greece) then Fuka, Libya and Italy (RSU). With appendices Note: Open in 1972 Date: 1940 Oct-1944 July Held by: The National Archives, Kew Might also help out understanding some of the abbreviations TD
