Here is a Luftwaffe claims list from April 21, 1945. Please note that Galland is the only pilot claiming a B-17 that day:

Once again I don't know how reliable this list is. What I do know is that records can be wrong and that things that were believed to be true in previously published historical works can subsequently be shown to be wrong or at least open to question. Here is a case in point involving one of my father's fellow pilots from the 7th Photo Group:
On 26 November 1944, Hermann Buchner, in his first operational sortie in an
Me262, 'Yellow 8', claims to have shot down Irvin Rickey flying an F-5E (P-38). The official reason for the loss at the time was flak rather than enemy aircraft. The well researched semiofficial history of the 7th PRG "Eyes of the Eighth" by Pat Keen and published in 1996 with a forward by Roger Freeman still lists the reason for the loss as flak.
Here is the source for the above claims list:
