Help needed for a sturmgepack

[jip]

Hello guys,
Last weekend I found a sturmgepack, it is modified but it seems very old and it's look s like the "German touch". May be taylor made during ww2.
It is very well done, and the aging is homogeneous.
I'm going to be a little lost and I need your knowledge.
Thanks so lot.
Here are the pictures.

Hi mate,

Unfortunately it’s totally rubbish.

A very bad ( and ugly ) fake/repro.
