Need some help identifying 5x7 camera

[OeT]

I just bought an old 5x7 camera and would like to know a little bit more about it.
Brand, how old it is, value, stuff like that.
It's stamped 5670 at the infront of the handle.

Some pics:

That's not a 5x7" camera as such - it's probably a 13x18cm "Reisekamera".

Most of them were made between 1900 and 1950, but there are both older and younger examples - and there seem to have been hundreds of makers, too. But they are great cameras to use.

I don't know the brand for sure, looks kinda like a B&J. I guess the hinge back puts it ~<1900.

P.S. Ole is right, it does look very much like a Reisekamera.
