I know , I would have thought the 1939 register would be accurate , my late fathers diary says they celebrated his birthday on 12 th October , it drives me mad.
I just found a post I made in 2007 on Great War Forum regarding those two slips of service records , I paid my money and filled in kinship forms to get those from Historical Disclosures and when I complained about lack of content they said " we suspect some serious pruning by the civil service went on "

I thought the 1921 census would come up trumps , I counted the days down from about 4 years away !
