Sean Turvey's Comments

I was able to find this in Model Engineer Magazine from 1986 but it is older than that as I had that tee before 1984.

The nut is called a Penrose hexigon named after the mathematician Roger Penrose in the 1950s. The bracket is also by Penrose. The earliest reference of the support I could find was from the June 1964 issue of Analog Science Fiction and Fact but I have a feeling it is older than that.
