OK so what the hell is this? Unembossed, CD 145, light aqua. It does not look like an [010] American, [015] Brookfield, [020] Grand Canyon, [025] Pennycuick, or a Canadian. It does not have the Brookfield 4 tiny drips, or the Canadian band on the skirt, nor is it a MLOD???? It does have some fine machining marks on the bottom of the skirt. The inner skirt is recessed almost as if it is a CD 143, but it is not. The mold lines go up to the top of the wire groove and make a circle. Then there is another mold line on the dome that is just a circle about a 1/2 inch down from the dome. There are no mold lines from the top of the wire groove to the circular mold line around the dome. Pardon my O.C.D., but this one has me stumped. Maybe Grand Canyon????
