The Silver Glo CRT Company.

(Responding to a two-month-old post, that responded to a near-thirteen-year-old topic...)

This company name "Silver-Glo" seems very familiar, something like a family member came on this forum (or ARF) with a fairly big stock of unsold CRTs, perhaps ten to fifteen years ago, and the discussion got far enough for one or more people to buy CRTs from the old stock, and report that they worked well in the set(s) they were put in. And, Indiana versus Canada seems correct, too.

Maybe the discussion can be found in a search?
