I picked up a set of SE 255 cams on ebay. They were listed as "CVO-255" on the auction, and that is inscribed on the lobes, but the box is for a different model number.

I would assume that if they have CVO255 inscribed on the lobes then they're 255 cams, right?

 

Were they new or take offs? If they were take offs, could be they just put them in a box they had handy.

 

Used. I figured that they might have been thrown in a spare box, just wanted to confirm.

 

They are 255's. Like RDM said, they were most likely packed in a box they had on hand, most likely from the cams that replaced the 255's
