An unknown Identification's plate from a Luftwaffe's a/c

[loiclemarchand]

Hello all,

Could it be possible to identify this plate from a German's fighter plane crashed in 1943 in Normandy ? It will be a great help.

Here some info about the fate of pilot and a/c :
-a/c (109 or 190) was shot down by an allied fighter
-pilot killed
-pilot recovered by Germans after the crash
-date of the fact unknown

Here the info on the plate :

Sach Nr : 109.621-02
Werk Nr : 27675 / 1248
Hersteller : Jau

Well anyone know what's that ?
and if there is any luck to identify more precisaly if it was a Me-109 or a Fw-190 ?

Could it be possible that the Sach Nr corresponded to a Me-109 because 109 appears ??

Any help are welcome and much appreciated.

Thanks in advance

Regards

Loic
