Hello Edward
It appears that he did not claim any success against the Western Allies. The situation in the west was vastly different from what many veterans from the Eastern Front were accustomed to and sometimes they had a rather difficult time adjusting to such. Perhaps Reiff was one of these? Here is what I hve been able to find on this particular pilot. Any comments or corrections would be appreciated.
