This is an Aqua CD 121 in what appears to be EIN  (F-Skirt) HEMINGRAY (R-Skirt) No 16 SDP, but take a close look at the embossing: the letters MIN in front are all connected, and the N in the rear is also somewhat filled in. I don't know if it's a "mold paste" issue, damage to the mold, or some other manufacturing anomaly. It is different, though. The halved drip point under the H in front is the only damage. There's also some tiny bits of white firebrick floating all around. Anyone want it for $5 plus postage?
