Slowakische Kassettensite mit allen Einlegern

[EZ647]

Preparing for the 06/2024 update, which will be done in about 1-3 weeks.

FirstLine Cromo are ICM audio cassettes, each in a slightly different design with different hubs.

What I don't know and need advice on is:

Ampex Professional, year?

The green cassettes with no brand, is there an address to GB, what should I list as the brand and other details?

Regards EZ

I also forgot to ask for the correct year for the ICM superferro cassette.
