The left one is a CD 166 [010]. The right one is a CD 161 [010]. Any help on the exact colors would be appreciated! Also, the 166's base is ground down all around it. Could this have been a factory done procedure? There are also two small cracks in the back that are spaced out like the glass expanded and cracked and then cooled this way with a small space between the two sides of the crack. Any ideas? Thanks to Brent Burger, it has been determined the 166 is a Rosy purple with a touch of smokiness, and the 161 is a plum or perhaps dark plum.
