I don't recall asking this question previously, and apologise if my memory has let me down.

The service records of 'my' men joining the RAFVR at the start of WW2, invariably record they enlisted during the second week of August 1939, but did not report for duty until between 5-10 September. I assume the latter is connected with the declaration of war on 3 September and the immediate enactment of the National Service (Armed Forces) Act, which imposed conscription on all males aged between 18 and 41.

I would appreciate advice as to why, or by what authority, did so many enlist the previous month.
