Hi
Where did you get this record from? I've just looked at the CR2s on Find My Past and there are 2 CR2 cards for a J W Thorpe, both have a Dis.A. No of 1039964 and Seawed would be able to confirm but I think these numbers were individual to the seaman.
The first is stamped 05 Nov 1924,rating- asst. steward and the stamped ship number is 145419, the reverse (?) of the card has also been scanned. That lists 7 other ship numbers and voyage dates ranging from 04.02.22 to 03.03.34.
The other one is for the same name and Dis A No and is date stamped 25 Jul 1934 - rank waiter. stamped ship number 140517, no other voyages listed.
I hate to rain on the parade, but as you have his enlistment into the Tank Corps (which shows his mother as N.O.K.) on 18.10.1927 and a discharge date of 17. 10. 1933 this seaman's record is not at all certain to be for your J W Thorpe?
