Maybe I'm duped but I think they suitable for "display only"...if you used them "for years" with no problems then good on ya, mate!

"Talking to the KoolStop people at the annual bicycle trade show, I
learned that it is a KoolStop formulation and that they make pads for
most of the smaller brand brakes, including Matthauser. You might
recall that the Matthauser brake pads had cooling fins on the rear.
This was as scientifically incorrect as the compound. Effectively no
heat passes through the brake pad that is an insulator. The heat must
go into the rim to be dissipated."
As with all things Brandt and Controversial: YRMV. (but what he says here makes sense to me)

I remember when Jobst wrote that thing about the cooling fins. He's right: I have observed that rims heat up, not brake shoes.
FWIW, I had a set on my old Bob Jackson, running them on Mafac Copmpetitions and sew-up wheels. I went on a killer century in Santa Barbara many years ago that included a run down Gilbralter Rd., which goes from Camino Cielo on the top of the ridge to close to the Santa Barbara flatlands. It is steep and curvy, and you better have some clue about what you are doing. Either that or not care too much about your personal well-being. About half way down, I looked down at my front wheel. The heat from braking had melted the glue
and the tire had rolled about 90 degrees so that I was riding on the sidewall.
When I managed to get stopped, the rims were burn-my-fingers hot, and it took a while for them cool down enough so I could reposition the tires. (It took me a little longer to get up the balls to resume heading down the road.) The brake pads and holders? Cool as the other side of the pillow.
No this doesn't prove anything and the story is worth exactly what you paid for it. but it consistent with Jobst Brandt's position.

Those are the Rainbow Jersey World Champion colors that winners of the - wait for it - World Championships every year get to wear for the next year.
