That's not just the code for an Anthracite City - it's the code for ANY City that was produced in the 2007 1 season. Still, that will at least help distinguish it from Plomb (a color that is often mixed up w/Anthracite), which is the 2007 3 season.
Anyway I was assuming that this Barney's SA meant what is the
Barneys code for Anthracite, in which case we're probably out of luck. Doesn't he know his stores own darned codes? Sheesh.

Well, I know what the problem is - Barney's probably calls Anthracite "Blue" ... so he doesn't know *which* blue code to pick.
