Luftwaffe claim 1 Jan 1945 - BE-NL border area -'Auster' type

[Leendert]

Towards noon on 1 Jan 1945 two Bf-109s shot down an L-1 Vigilant of the USAAF 125th Liaison Squadron, making a routine flight between Maastricht (NL) and Liège (BE). One occupant of the light plane was killed (S/Sgt William W. Fletcher), two more escaped more or less unscathed.

I wonder if any LW claim has survived that points to the location of this shoot down? More often than not, LW-claims of US L-types (L-4 Cub, L-5 Sentinel...) were also reported as 'Auster', so references to latter type may be useful as well.

Any leads welcome, thanks.
