Tanker Grey Rules! Just wish I could find a Battle mistress in tanker grey... That would be amazing! Is there a such thing?
I never saw the dark "Tanker" gray color until after Battle Mistresses went out of normal production -- as a matter of fact, I believe tanker was considered a new color at the Fall 2008 Knob Creek show. I remember a tanker HR in the VetDayGanza, and of course there were tanker NMSFNOs, but I don't think there were any tanker BMs (unless they were made as one, two, or three offs for Knob Creek -- I don't remember them, but that wasn't what I was looking for).
There were lighter "Urban" gray BMs; I own a pair of urban FFFBMs with blue/red mag handles. I thought those handles looked better in the online pictures -- I can see blue/red in strong natural light, but they look more like dirty purple indoors. I thought that it might just be dirt and oil from the shop, but it didn't help when I cleaned the handles using alcohol.
EDIT: I just looked back through my Spring 2009 pictures and didn't see any of the BMs in tanker.
