Hi, The cards CR1 and CR2 are only one part of his record. These cards refer only to service prior to Jan, 1941. There are two registers of service that cover merchant seamen's records for the 20th Century, namely The Fourth Register of Seamen effectively [1918-1940] and The Fifth Register of Seamen [1941 - 1972] If you only look at FindMyPast you will not get his WW2 service file.
John Walsh 3rd Engineer was killed aboard ss FORT CREVIER in the huge Bombay explosion aboard FORT STIKINE on 14.4.1944. He is mentioned by name here:
http://merchantships.tripod.com/fortcrevier3.htmlHis service record [CRS 10] from Jan, 1941 should be held at Kew in piece BT 382/1874 -
https://discovery.nationalarchives.gov.uk/details/r/C10990099 best obtained by visit to Kew but obviously you will have to wait until the present emergency is over.
This is a breakdown of the cards - note they will probably contain some mistakes and omissions and not a true voyage record of his early service but it gives you a start.
119878 – STAGPOOL – 4.1.1930
132822 – FISHPOOL – 4.9.1930
139228 – ROXBY - 2.1.1931
139248 – ULLAPOOL – 30.12.1931
127464 – LEVENPOOL – 16.4.1932
127464 – LEVENPOOL – 19.9.1932
139258 – KIRKPOOL – 30.7.1935.
As I said you will need his CRS 10 for service during WW2.

Hugh
