My grandfather passed away many years ago. This photo could be him so l thought l would see if anyone could identify the uniform. l don't have the orginal just a this. l appriecate all the help
So it seems as if it is a uniform from WW2. Grandad did received British War Medal and the Victory Medal from WW1. As of his generation he did not speak of his war. All bar one of his children have passed away. My auntie thinks it is him but she was evacuated for the duration. She was a small child. I have added a picture of him in 1953, to see if anyone thinks they could be the same.
