Bag

[Kakukk]

Hy guys!
I have got 2 of this bag.It is from my grandmother's house,my greatgrandfather use it until he die.My grandmothers says the germans left in the house in 1944.
I am searching on the net about information but i can't find any same bag,every has got some distinction.
In this picture you can see the bag which is in better condition than the other. The black belts were change by my relative.
If anybody has got any information about same bag or any other which looks like that pls comment it.
Thanks.
