I could have sworn there was an orange COPO at an SCR with a 72-72 trim tag, but I may be (and probably am) mistaken. So I guess the only 72-72 COPO Chevelle I know of is this one right here...but I still think that's what it is.

Its quite possible (and IMO, likely) that this particular car doesn't follow the "accepted" norm for trim tag coding due to the low number of COPO cars produced at this plant, in this color. Lots of production/assembly line parts and assemblies for a COPO would parallel what was used for an SS, trim, hood, required options, etc. So it's quite possible the tag was done the same way an SS would be done if whoever was doing it wasn't familiar with the "norm" for coding a COPO car. That's of course if this turns out to indeed be a COPO!
