Earthworks,
I've got a couple packs of blades from the same era. I tried to shave with them for a while because the razor was so cool. Plus I figured the blades were new enough and I had plenty. All I can say is that guys were a lot tougher back then, or else the blades got dull over time. It felt REAL good to go back to the modern ones. I ought to send you a pack.
