I just checked the London Gazette and it would be more correct to say that W J Daley was 'commishioned' in the RAFVR with the number 101457.
As an enlisted man he would have had a different serial number, assigned to him at recuitment. At the time that his commishion as published they were not yet publishing both the NCO and officer numbers in the notifications. See page with his name second row from end of asecond column.

Going back to my pedantic corner.
