If I remember correctly, those replaced the Gillette Super Blues when Wilkinson sword took away most of Gillette's business in the late 60's/early 70's with their stainless steel blades. The early stainless Gillette blades were okay, but not as good as the Wilks. If those are later blades, they should be decent shavers. Beyond that, I really don't know. Heck I don't even know how accurate the information I just wrote is. 0300 hours here. Time to call it a night.
Thanks for your effort, and good night I've got 69 of these bad boys on the way, so hopefully they will be good
