Already had a look when finding the info on the Ju-88.
Although the crew of the Ju are named, and a brief description of the 'combat' and the crash, I didn't find any further info on the Havoc.
It seems that the Havoc probably didn't actually shoot down the Ju-88, which was seen at 15,000 feet, and the Havoc climbed to attack., when the Junkers dived away almost vertically, the Havoc following in pursuit.
The Havoc pulled out of the dive on nearing the ground, but the Ju didn't, carrying on at great speed, being almost entirely buried,
Apparently. a claim was also made by an A.A. unit over the estuary, as the Ju-88 approached from the south west.

It's possible that the Squadron ORB may show either the individual code letter or serial number (possibly both, although this is rare), and these can be accessed at the National Archives, Kew, either in person, or on-line.
