My sister wants to commemorate my grandfather with a tattoo of his service number and an anchor. How do we find out this? We don't want or need the whole service record, and I don't think she would be willing to pay a fee for it anyway (certainly not if it is £30 like the Army records when I enquired about my other grandfather). He was born in 1929, and so served post-WW2, married in 1948, and didn't stay in the service long after this. My uncle has been going through various stashes of paperwork in the house but doesn't seem to have found anything Navy related.
