I got these 2 pieces from different states and they are mold matches from one mold. The colours are ice blue and ice aqua but they look extremely alike in certain lighting. The ice blue I picked on the line next to my house and the ice aqua from a line in another state. Embossings on both are:(FS) HEMINGRAY-42 / O (under main embossing)(RS) MADE IN U.S.A. Round drip points, no numbers and dots but just an O under hemingray on both pieces. Also, the G's on both pieces are raised in the same position on both slightly above the N.I cannot really find a thing wrong with either of them. If you specialize in mold matched insulators from one mold, here is a nice pair of them for you. $7 + $8.10 flat rate shipping in USA for the pair.
