Greg and others, We sold the Bris for many years, and there was no silvering on the glasses. The glasses were smoked glass, although the very first ones had clear glass for use with stars. I just spoke to Sven Yrvind on the phone, and he still makes 1 or 2 per year and sells them personally. He did say that at one time after he went out of formal production, he experimented with a beam splitter coating. So maybe you have seen one of those.
