I could send you a photograph if you think that would help with recognition?
Not by email, I'm not that clever I'm afraid, so would need your address.
Also I failed to mention that John's wife, known as Rita, was a nurse on the ships with John until the rules changed and spouse's couldn't work on the boats together.
Could send a photo of them both?
I phoned Kew and National Archives and they politely said there wasn't much chance!
Looking forward to hearing from you,
See John Harris
