Nothing I see on Boyd's or Foose's site resemble those, possibly an older OOP Boyd's design. or maybe custom. I like the way they did the center to get 4 lugs on a five spoke wheel, most of the time it just looks weird.
They are an older smoothie 2 as a bunch of us has mentioned . Type them in google and they come up . They do look weird honestly especially with the 4 lug . Much nicer wheels out there
