Wreck of Bf 109 G6

[gradoli.v]

Hello,
we are a scuba diving Association from Montalto di Castro, Italy, a small town a hundred klometer north of Rome.
Last summer we found a wreck of Bf 109 G6 under the sea level (-26 meter) in front of our coast.
We still have not found the Werknummer yet, but we think that it is the Hans Joachim Kautz aircraft from 3./JG 77 shut down on may 15, 1944. On this day we know that this pilot had a air combat with some Spitfires above the Bolsena lake.
The pilot has been last seen by the coast . We have not heard anything neither about the pilot nor the aircraft ever since. We have also a document in which it is confirmed the presence of pilots of the 244 and 322 Wing on that same day. Would it be possible to obtain the Daily Operation Report from may 15, in order to verify whether a Bf 109 was shut down and ended up into the sea?
Any help on this matter would be very much appreciated.
Thank you very much. Best regards
Vittorio
