something i know a bit about, in 1945 the 8th Army was in Italy, the Egypt push ended in 1943, there was 13 units that went through the 8th army, been though all of my books and can't seem to find any relevance date corresponding to the date on the ashtray , but the date could be a US date so it would be 7th June 1945 and it could relate to the 8th US army, but you have to think that WW2 in Europe ended On 8 May 1945, that's why i think it could be something to do with the US, as the war in the Far East was still going on until 15th August 1945 and Japan formally surrenders on 2nd September 1945
