I cleaned the spinners, they had little grease inside the thread. I guess maybe a one time use for a demo car etc.
And yes they are slim. With the TRIGO spinners the collar is edge to edge. With the Halibrands I can see 3 pitches of the spindle thread. And they fit!

I don't know if I will used them. If not, how much are they worth? Any offers?

They offer on ebay fake Halibrand spinners with wheel covers for 1.5k Wow!
