I've only handled a handful of DCs, Chuck!
(Like I posted: They never really needed me.)
Note from my previous pics that the 9_A stamp is adjacent to the bleed facets, whereas the two earlier Big Twin discs are traditionally-stamped opposite. It appears there were at least four different 9° discs. A quick shop search didn't find one, but I did find two 8° discs in a buddy's pile o' M53A-1s, and they also have double facets, although a shallower angle.
Its gotta be a turbulence thing.
