This OB is fairly well known with a gray glaze but brown ones are another story . The gray ones were found at several locations in Eastern Washington but the brown ones seem to be really illusive ... in fact prior to this the only ones I ever personally saw were in active service in a small sub station south of Colusa, Ca. . This is the first one I have seen found in the Pacific northwest or anywhere in the Seattle area. it's not pretty or as attractive as it's gray counterparts but it is definitely an odd duck !
