Slowakische Kassettensite mit allen Einlegern

Yes, this is a Magna. The quickest way to distinguish them from similar BASF and ICM is that the scale under the window (100-50-0) is divided into 20 sections, not only the usual 10.

Hubs and slip sheets were parts which Magna didn't always make themselves, which is why you can find quite a variety of both in these shells. The white spots on the tape could be binder breakdown and a hint on Agfa tape, but not necessarily. Magna used some "mystery tapes" from different sources, and not all of them are stable after 40 years.
