just a variation on the Super Pista I guess, but predates the one on modern models with what I'd call a "Tri-Wing" base. The rest of the package including wooden handle is regular "Super-Pista"

backing paper peeled off and lined up on the stay, only the center of the tape is stuck down at first. I smooth that strip with any smooth plastic tool at hand, ideal tool is a "bone folder" but for this I used a paint brush handle

Here's the chain stay on a Univega for this demo, it's cleaned with alcohol but paint is chipped so final result will not be ideally smooth

taped to a cutting board, Stay Tuff aligned with one edge, you can get 2 out of one 2" wide piece, so why not?
