If they look decent, use them! Spoilers are simply fantastic. The Super Stainless blades with the "miracle plastic coating" were produced from the late '60s through the mid-'80s, picking up "the Spoiler" marketing tag somewhere along the way.
Thanks John! I used The Spoiler in my '57 SS. Sometimes with razor acquisitions you get a partial pack of old blades. I thought about saving them but figured I might as well use them. I guess if someone out there was into collecting vintage blades and dispensers I could trade them.
