Hi Nivard Thank you so much for your answers and link. So informative and helpful, as always. I have downloaded the document - very few details on it and no mention of the first regiment but that is fine. His daughter will be very pleased just to have her memories clarified. Rather sadly, he died falling down a mountain in 1946. He and his daughter went on a walking holiday to Switzerland for her 21st birthday - she stumbled and he went to catch her and slipped himself. No, I have not managed to find his medal card either. I found his two reg numbers from firstly a postcard addressed to him from a friend and the second regiment number (which is the one on his records - 25051) on a letter from the appointments officer to the Commanding Officer of 51st Batt R Warwicks. His daughter never mentioned any medals but he must, at least, have had a service medal. With my thanks again for your kind help.
