I can find a "Seaman's Pouch" for him although he is listed as E S Taylor. Every other detail, Dis A number, Date and place of birth is correct.
http://discovery.nationalarchives.gov.uk/details/r/C8150335Seaman's Pouch's,
These records relate to individual seamen. Documents were filed together in paper envelopes known as pouches. The contents vary for single registry cards to ID Cards, photographs, letters, applications forms and other ephemera. The records cover the period 1913 to 1972 so it should cover the whole of his seagoing career.
The main document you need to look for is
His Form CRS 10
It is probably here
http://discovery.nationalarchives.gov.uk/details/r/C10989989If not it should be here
http://discovery.nationalarchives.gov.uk/details/r/C10991187It should contain the following information
The front page of the service entries includes the following information:
•Name •Date and place of birth
•Discharge 'A' number
•Rank or rating, with relevant certificate details
•Details of any other qualifications
•Date CRS 10 first page was created
•British Seamen's Identity Card Notations. The entries refer to correspondence and issuing of cards, certificates, applications etc. The originals in general do not survive except where they have been filed in the seaman's pouch. See below.
•Merchant Navy Establishment [licenced] Agencies (MNEA) Contracts
•The continuation pages show: A list of ships and their official numbers with date and place of engagement,
•rank or rating,
•F or H (for Foreign or Home trade voyage),
•date and place of discharge from the ship
•character grade
•National Insurance contribution code
•Registry clerk's initials and date of the entry.
•When ashore the sheet may bear the entry MNRP (Merchant Navy Reserve Pool) with date and place.
YOU CANNOT SEE THE RECORDS ONLINE
CRS 10's are stored alphabetically in blocks of 60 names therefor you cannot access an individual seaman. CRS 10's contain sensitive personal information and I suspect, been used in the past to commit Identity Fraud. TNA take security to the higher limit when they receive requests for CRS10's. Your best bet is to visit Kew, trying to get the National Archives to search for you can be an expensive nightmare.
The procedure is somewhat complicated but TNA staff are very helpful and you should not have any problem. After you have obtained his CRS10 you can then go on to view Crew Agreements and Logbooks it all depends how deep you wish to go with your research but one of these documents should tell you the place of leaving his last ship. If indeed he did emigrate.
