The Michel range for that set is 83-97. The 75pf (Scott 90) is Michel 104. Michel also distinguishes between A and B types for the higher denominations (94-97), so 94A is 26:17 perforations, whereas 94B is 25:17 perforations.
My Michel catalogue is from 1970, so apologies if Michel has changed any of this since then.
