Hi Mando,
The wheels are from Vintage Wheels US
http://www.vintagewheelsus.com
My wheels are still in California. I spoke to Bob last night and they should ship in a day or so.
Looking at your gallery your wheels appear to be bolt on. Mine are knock on. Vintage Wheels do make bolt on wheels now and perhaps the spinner supplied with these will suit your purpose. Is your intent just to find a 'flatter spinner' to bolt to your existing wheels?
I can talk to Bob again tonight and ask him the question.
Cheers
