were the Bear Razorheads when they were in stainless but still a glue-on?

Thank you Jack.

You may be thinking of the first Super Razorheads, they were sold from about 78 to 81, then the blue ferruled screw in Super Razorhead appeared I believe.  Almost all of those were sold with adapters installed, but heat will remove them and you have a glue on head.
