Single roller with 1-1/4" roller. could not find any other markings except on the glass - "3/16 U Permaglass tempered safety USA Z97-1-1966". So, my guess is Circa 1966? Any help is much appreciated.

I'm afraid we don't have this exact roller. That said, other customers have used our 81-256 as a replacement. See what you think.
