Hello again,
my first post was written (mostly) from my mind. Now I can give you a concrete source.

Chris Shores wrote in "Fledgling Eagles" (Grub Street, 1991, page 72) about the air fighting between GC II/4 and JGr.176 on the 27.9. According to this well researched source Baptizet, de la Chapelle & Tesseraud claimed 3 victories. The first as probable over Hornbach - the Bf 109D force/crash landed near Bad Homburg with 50% damage (also Chris Shores is not believing the 5% story, maybe he had a better document?). Then the French formation followed the Messerschmitts to the Lahr area, where 2 confirmed Bf 109 were claimed. Both Messerschmitts indeed went down not far from Lahr (Rhinow at Triberg & Köpke at Unterharmersbach).

I think the date conclusion made by Chris Shores is right (27.9., not the 29.9.). The area of the air combat (Lahr) agrees well with the area of both Messerschmitt losses.
I can confirm that the OKL loss list contains many such date errors (it is not an error actually but a delayed report going to the higher staff). For example we can take the 29.9. again. There is a loss of a Do 17F from 1.(F)/124 (40% damage). But this accident happened one day earlier, on the 28.9.

I hope this will help and make air fighting researching much more productive.

Best wishes,
Marius
