That number in the shell on the Basf LHMI 60 large window cassette is 54 on the left and 4 on the right, on the opposite half of the shell it's 54 and 3.
The guy who sold me this cassette in 2013 said he bought it off ebay as a 10pack from Portugal some time ago. Unfortunately there is mold on there.
The latest addition to this LH Maxima I family will be two C90 cassettes with a small and a large window, both Made in Germany. (next update)
I still want to ask how the composition let iron oxide with cobalt, or did Basf already have a name at that time? Megadium probably not yet, or did it?
