Apparently, certain models of Lotus cars from the late 70s and early 80s used a Triumph-based steering column - including a horn-button which is identical except for the logo.
A friend of mine, and a member of my Triumph club, happened to get hold of a box of several dozen Triumph horn-pushes, which he advertised for £1 each. He was approached by someone from a Lotus club, who bought the entire box for a slightly reduced price, replaced the Triumph logos with Lotus logos, and sold them on for £20 each.
I'd guess the CAA/PFA thing is the aeroplane equivalent?
