Hello kaki3152
Unfortunately I cannot help you with his last victories past early July 1944 but here is what I have been able to find on this notable ace. I have compiled the victory list from Prien, Wood and Arthy/Jessen. Notice that there are several differences from your list and I hope this helps you. Any comments or corrections will be greatly appreciated as well as any additional data regarding his victories or loss list information.

Edit: I have updated the thumbnail biography with new information concerning his early career as well as the corrections/additions mentioned below thanks to kaki3152 and Kapper.
