Wow, they're pretty damn mint for 7400! Those are totally DA rings; look how smooth all the edges of the chainrings are. Pretty sure those surfaces are rough on a nice shiny tricolour chainring.
I bet the cranks aren't even scuffed, huh? If they are, these rings would have to be replacements.

Bah. Those chainrings are like 1/4 used, max.
