JG53; losses or victories on nov 25th 1944?

[Flyingkag]

Hi,

I'm investigating about the US pilot Skenyon, Leo Francis,162nd TRS, KIA on nov.25th 1944 in the area Strasbourg, France. The MACR gives that Skenyon would have been shot down by "20 Me 109" around 12.25 in area Haguenau (near Strarsbourg); apparently the JG 53 was concerned, and would have lost one plane in the airfight. But no victory is given to the second US pilot that survived this airfight; my questions;

-are any BF109 of JG53 missing or touched in action at this day around 12.25?
-is one P51 (F6) "officialy" claimed at this day around 12h25-12h40? (two pilot of JG53 pretend have shot down the same Mustang)

Thanks for help;
