Well the one I have (previous post picture) as I have said is a black pewter yellow belly (Black pastel / Pastel / Yellow belly) not cinnamon. I know black pastel and cinnamon are very close though but they are very different. I highly doubt that it is the start of a ringer that didn't completely form because these faded patches are very common in pewters and never have I seen a pewter with a full blown ringer. It is just a pattern that is random, kind of like patches on a piebald, you never know where the patches will be and how much.
