This may be covered in the web sites John mentions (with my elderly browser
I rarely follow these up), but there is another probable ancestor of the
"duct/duck" tape that holds the world together today.  This was a gray,
cloth tape with a water-based adhesive that was used to seal the joints in
furnace ducts conveying hot air up, and  cold air back to the plenum.
