I’ve been helping some friends move. Ikea furniture reminded me of this gem.
If anyone can find the original source, I’d be greatful.

Good luck finding the original of that. My dad had a photostat copy of that up in his workshop well before I was born. And I’m not exactly young.
Yeah, the best I could manage was that the term “Trichotometric Indicator Support” first shows up in print around 1965 in “Machine design, Volume 37” and “Road & Track, Volume 17”. Chances are the drawing existed before that, though.
My brain hurts now.
