Bf 109 loss July 4 1944 Normandy

[Orwell1984]

Hi everyone
A user on WW2talk forum is trying to track down the identity of a BF109 credited to his grandfather's LAA battery in Normandy on July 4, 1944.

Here's the location details as clear as possible:

The War Diary gave the the coordinates of 922784 and the LAA battery were based at Lantheuil, Normandy. Having played around with a coordinates translator website, I think the prefix to the numbers would be VT 922784 which then translates to 49'16'13N, 0'31'08W which looks to be in the right sort of area, but I am not sure how accurate that translation is.

Any help is greatly appreciated.
Thanks
