I’m researching my family tree and I know that my Grandad was in the RA from 1939 and came back to the UK in 45. We have his service number, but there aren’t any records showing his time there. We have photographs that prove he was there. Could anyone give advice how I might move forward?
Not to dissuade expert answers, but have you looked at the Ask Historians Wiki->Military Records->United Kingdom? There may be some helpful information while you wait for someone more knowledgeable
