in australia i would say the malvern star 5 star track frame, or maybe the skidstar. eccles would know more, and may have examples! but for me its my speedway, the only one ive seen, maybe the only one ill ever see.
mines a dayton d-4(ill try to find an add with a stock one) although i do own one but its not complete and as i last heard mine made up #21 of known survivors...
so i guess i found 3/4s of the holy grail :mrgreen:
Not impossible to find, not even slightly exotic, has those silly 571 rims, but it's still the quintessential gold standard American cantilever coaster-bike.
