Universum-Cassetten (und andere vom Versandhaus Quelle)

[Kirunavaara]

That red "Super" is nice, it's from the line-up after the one I just showed, but my examples all have black shells I think. The black Low Noise was offered from ca 1978-83. Both of these have Permaton shells. Tape could be a basic ferric like Agfa PE 66 (Low Noise) or PE 68 (High Dynamic), or BASF LH. Usually you can find out by comparing the looks and the smell :-)

The light grey version belongs to the first Universum line-up; these also exist as demo cassettes delivered alongside with cassette recorders, which means they weren't necessarily made by Maxell, and they didn't come with a case and inlay. I guess we have either an alternative Japanese manufacturer here, like Columbia, or someone from Korea, Singapore or thereabouts. The manufacturer of the tape recorder it came with might have chosen the source themselves.
