No, you have to go by the blade itself & in your photo they are the successor: SPC's. Some leftover 74's were produced in the successors packaging though. As I've stated in various posts I prefer the later SPC's myself even if they don't last as long. Even those that pop up are being snatched up on the bay now for more than I feel they're worth.
So there was still Tungsten in the successor blades, as the copy on the back of the package asserts?
