If you have seen the London Gazette site, you will have seen your uncles Service Number (142249). You will note that the L.G. was published on 8th June 1945 with the Supplement dated 14 June 1945.
With that information and at a cost of at least £30 you can go to the Ministry of Defence website (veterans) and obtain a copy of his Military Service Record of where he had been.
Veterans’ site is at: http://www.mod.uk/DefenceInternet/Ab…erviceRecords/
