I really don't think that this can be determined definitely, as I said, there are many possible/unconfirmed kills. These are the other candidates, but none of them flew only the Me 109?!

Maj. Anton Hackl, 34 4-mots, 192 total
Oblt. Konrad "Pitt" Bauer, 32 4-mots, 57 total
Obst. Walter Dahl, 30-36 4-mots, 128 total

Bauer is not so famous, so you probably don't mean him. Is he one of the three?
