Washington Water Power used a lot of mud ponies on cast iron wall brackets as service strikes. Most were brown, and occasionally a grey one is found. In many years of hunting, only a handful of these unusual blue ones have surfaced. The color is not cobalt, but a blacker, more "indigo" color, much like denim jeans. The glaze is thin and grainy, making for a color unlike any I've seen in a mud pony. Condition is close to perfect. $35 post paid US
