Engineering Sample
I have SEVERAL of these. They do appear to be sample units - mine has an "ES" (presumably short for the classic "Engineering Sample" stamped into one of the heatsink fins. Presumably, this is the mating of a prototype heatsink and a finished (i.e. qualification sample) processor.
