Hi, I am researching my Grandfather at the moment. My grandfather served in the royal navy during WW2. He volunteered when he was 20 years old. Unfortunately he passed away when he was 32 years old, 2 days before my dads 2nd birthday. We no very little of him. we do have his service records from the war, and I am trying to work out what they mean. I am uploading it here, in the hope that someone could help me with it? Im finding the writing quite challenging to read so any help from anyone who has an understanding of it all would be amazing - thanks in advance His name was Andrew Irwin, from Rutherglen in Glasgow Born in 1921, died in 1954 There is some writing at the top of the page, that I cant undertand? Then it mentions "collingwood" - which I understand is the training base in Portsmouth? The "substantive rating" - could anyone explain what this is? And then the rest, Im unsure if these are ships? or bases? and I also dont know where they are? I have lots of photos of him, on ships - with other men, so would love to share these & see if any of the other men could be identified too.
