Sure will!
The Topco blades look for all money like Vintage Crystals or otherwise what we would call 'Israeli Personnas'. It has the same 'Super Platinum' printing on them, although I can read 'Made in USA' on them so it could be before they opened the Israeli plant. Should be a pretty decent blade, early to Mid-80's vintage I would say. I would happily use them.
The Wilks are more recent - you can buy them on eBay, although these are not current production. I can tell they are older blades due to the font on the front where it says 'Fits all double edge razors'. It's Swiss721BT, rather than Arial/Helvetica which came into the printing game later on. Also these can be accurately dated to a 7-year period due to the printing on the back. There is an address for Warner-Lambert. Warner-Lambert was a pharmacetical company who bought out Wilkinson Sword in 1993. They also bought Schick around the same time. Pfizer bought out Warner Lambert in 2000, so these blade are from within that period. These are Soligen-made blades, they perform ok.
Finally - the Personnas. These are the equivalent of the Personna Super Stainless I sent out in the vintage blades. Markings look similar, and I think they are later production. They may have a PTFE coating (Teflon to everyone else) due to the 'Glydex' logo on the pack. I think they would perform better in the glide stakes than the ones I sent out which were uncoated. These would be the pick of the bunch and I am definitely wanting to try them out.
