An interesting comparison: Gillette blade tucks were much bigger back in the old days (but the blades were the same size). This old tuck of Super Blue blades comes from the 1970’s. Here is a comparison against a modern tuck of Gillette 7 O Clock Sharpedge blades.
Interesting that the old Gillette blades were still carbon steel blades. Wilkinson Sword were making stainless steel blades from the 1960’s.
