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

I think around 1983/84. 

About the Cromo: Hipfred (he is also here in the forum from time to time) has discussed ICM in great detail, including the Cromo. Maybe he knows more. His facebook group: https://www.facebook.com/groups/481191722798703
