Who shot down 7th Sept 1939 near Warsaw

[Marek Rogusz]

Hi to all,
I am looking for information that could help to determine who could shoot down PZL.23 Karaś from 55 Bomber Squadron over the village of Nowe Grabie (circa 24 km NE of Warsaw) crew Pytlakowski, Zarzecki, Iwaniuk. Polish bomber was shot down by fighter (not sure 1 or 2 engine) at approx. 4-5 p.m. September 7, 1939.
Eye witnesses confirmed, that the whole incident took place very near in time and space to fight where 3 PZL.37 wre downed near Radzymin by ZG 1. That was just 8-9 km away from this event.
I thought about:
1 Ofw. Johann Klein 07.09.1939 Bf.109 E I./JG 76 16.45 Biala-Deszcze PZL P-23
2 Oblt. Werner Methfessel 07.09.1939 Rozan PZL P43
3 Hpt. Fritz Schleif 07.09.1939 Bf.110 C I.(Z)/LG 1

But…
Ad. 1 that was probably in another area, I am not sure.
Ad. 2 that was supposed to be in morning that day, probably?
Ad.3 no further info??? Was He shot down that day? But where?
Any hints?
Appreciate your help.
