Original m1895 tornister?

[Reichscollector]

I saw this tornister online. The seller couldn't tell much information about it except it being German and old.

I googled a bit around and I was thinking it maybe could be an m1895 tornister. Probably I'm not even close because this is not really something I have knowledge about.

There are a couple of things which made me hesitate.

First of all it is not marked. The seller checked but he couldn't find any.

Second thing, the color of the inside. Mostly you see them in a tan kind if color and feldgrau I guess it is. This one is also green, but not the one I see online.

I hope you guys will be able to help me out. And if it is a original tornister, is 40 euros a fair price?
