I am not sure this is the right area to put this posting and so i apologise if it is not, but i wondered if anyone could advise me how to find the army number of my father who served in the WW2 as far as i know he served in REME [some connection with Greenwich]. I know this is rather vague to say the least, but any help no matter how little would be appreciated, thank you [by the name he was known as Thomas William Cooper and lived in Hackney Wick London]
