Hi,
From your favorite Forum, namely TOCH: ...
The block is most probably 464047 to 464660, Erla Leipzig (Most probably Rasmussen info)
No Date given, but 1944 sounds good.
And most probably it was a Bf 109 G-14.
FW+xx None known whatever the subtype.
xx+FW : Three G-6s, only one G-14 ... with complete StKz but no WNr. given.
But

like Jim said, what's your source: loss list or photo?
A photo with a clear WNr. ?
Regards, Franck.
