North Weald 29/10/40

[Ivor D]

I am currently putting together the events of the LG2 attack on North Weald in the late afternoon of the 29th October 1940. Although I have seen some of the combat reports for the subsequent combat over the River Blackwater, those of some of the pilots that took part seem to be missing from the National Archives. In particular those of a 249 Squadron pilot Flt Lt Barton. Can anyone help with suggestions? Also does anyone have knowledge of the whereabouts of the 249and 257 Squadron dispersals at North Weald at this time?
