Hi Everyone...Still no further on unfortunately. No MN records for him at National Archives for WW11 service....Only his application and Seamans Pouch from 1960. No trace of him at Southampton Archives either.
No definitive answer on his RAF Enlistment Form Employer details ie Employer...Ind. O. 056.21. Dis, 123.....(need a code breaker I think). I'm sure there must be a clue in that...or maybe wishful thinking!
I wondered how he managed to claim his medals if he didn't have a Seamans Discharge book/number...even if he was an apprentice how would he have proved which ships he was on? That's possibly why he had to claim them twice...1st time under the name Santanna, and 2nd time under Macaulay (name changed 1947).
No idea where to look next apart from crew records....could be a long search.
