Grundig: The C60 is from ca 1974-78, the C90 from 1978-80.
Norelco is always US market, Philips used that brand in the USA because of a name similarity to the American Philco company; more details here:
https://en.wikipedia.org/wiki/Philips_Norelco
Early Norelco cassettes were imported from the European Philips factories. In the 70's, there was also a quite interesting series (Norelco 200/250/300/400/Challenger) which was sourced from different OEMs; I have found a TDK SD there, a Certron, and some US made shells, eventually loaded with Philips tape.

Ross: There are early ones marked Made in USA, Mexico or Portugal; these are mostly from Audio Magnetics. Later ones came from Hanny (Hong Kong) which through Swire Magnetics was linked to Audio Magnetics, because both companies were owned by the same guy. He founded Audio Magnetics, sold it to Mattel and built up Intermagnetics instead, which later became Swire Magnetics. Company address for Audio/Inter/Swire Magnetics was subsequently the same in Gardena, California 90248.
Expert: Yes, clearly Audio Magnetics, late 70's. That model is plentiful in Sweden. Expert seemed to buy from different OEMs for different countries in the 70's. Expert Germany had BASF cassettes, Expert Italy had locally assembled cassettes, Expert Sweden mostly Audio Magnetics and some Italian cassettes. In the 80's, Expert offered ICM made cassettes in some countries.
Boots: Yes, not earlier than 1982, but probably no later than 1984/85. From the mid-80's, ICM made a completely different design for Boots, still in Turbo shells.
