Early this a.m. I was looking at a un-fired NIB Spikes middy on one of the local classified sites, and what immediately struck me was that the upper had this same "plum" color. I thought it was very odd, and don't recall ever seeing that before, but didn't give it any more thought till running across this thread.
I was going to go dredge up the ad and post it here, just for illustration/comparison, but I'm thinking that's some sort of rule violation?
