I've only had two cook bros cranks, so I'm not the biggest expert on these. BUT it looks like these were originally purple anodized versions (based on the dust cap grooves) and someone has made red decals on them and painted them gray (or clearcoated). Someone that's not definitely cook bros. The quality of the paint/decals is not cook bros quality. And cook bros never used decals on their CBR's/RSR's, the text was always engraved AFAIK.
But with a polish (and maybe new black decals) these will turn out very nice!
