This set was in a TV repair shop in Berkeley, California until a few
years ago. The owner took it to the town's recycling center so that the
aluminum could be recycled. (Courtesy of Gary Schneider).
We know of five Octagons that survived into recent times.. One is at the MZTV museum in
Toronto, one at the Henry Ford Musuem, one at the Schenectady Museum, and
one with a private collector.
This was the fifth. At one time it was believed that only four of these
sets were made. However, the fact that 5 survived indicates the a fairly
large number were made.
