While working on the cassettes, a few observations and photos.
Ampex uses hubs, as do some Magnex cassettes. https://ez647.sk/cc/cievky/magnex.jpg
I'm sure I've seen the design of the unknown cassettes in the green packaging somewhere before, but I still don't know who could have made it. One of the cases has rounded edges, on a C90 like the modern packs.
ICM's FirstLine are typical chromdioxides except for the cassette with the older type hubs that copy the Basf design, but should be an ICM design, there is FeCo tape, odorless and translucent.
The covers all have rounded edges, on one piece the cover is dark.
No serial numbers on the cassettes, but ICM sometimes used numbers in this 1988-1993 period.
So I don't know I was going to put 1988-1990 on there, but I guess it would be 1993 and newer?
