Slowakische Kassettensite mit allen Einlegern

[Kirunavaara]

That one looks like the typical late VHS era generic shell, which almost all brands used, sometimes winding their own tape into, but more and more there was Saehan tape inside, as the other big players ceased their production.

You could look for a VHS license number somewhere in the shell, like LN 2xx, which may help to track the manufacturer.
