Thanks to all for this conribution.
What does surprise me on all the cross-referencs to the CD4 counterpart or USA editions is that the cat.n. are all over the place: doesn't seems that CD4 and Q8 were released at the same time and at the same pace, sometimes the CD4 cat.n. is lower than Q8, sometimes is bigger, as they were driven by two independent branch of Victor. Very messy history, would not be easy to find out the references.
