ORB December 23- 35 squadron Graveley. Gremburg/Cologne

I am researching my late fathers ww2 career. Has anyone got a copy of the ORB’s for 35 squadron pff at Graveley covering December 1944 especially the 23rd when a daylight attack with 582 squadron from Little Staughton and 35 squadron from Graveley attacked the marshalling yards at Gremburg/Cologne. My father was w/op on TL-J piloted by ‘Kiwi Lawson taking off at 10.42, dropping bombs at 13.01 and down at 14.18 but at Manston having suffered severe flak damage, the aircraft being written off, and my father hospitalised with a piece of shrapnel in his face-that proved difficult to remove-so it was his constant reminder until he died in 2003.
~I have gleaned these facts from ‘We act with one accord’ , ‘Heroic Endeavours’ and the BBC war memories web site. A look at the records would be the cream on the cake- so heres hoping someone can help.
My thanks in advance
Paul.
