Two of these Sapphire Blue CD 731 Tillotson's were dug in Augusta, Georgia last year by a bottle digger. The digger has found lots of rare insulators and bottles in the past. I got this one from him and this is the information he gave me on how it was dug... "It was dug with the other one, I haven't ever seen another piece of one. It was dug in Augusta, in a 1900-1920's bottle dump. I do not understand them being in that new of a dump? The two were turned up together digging with a back-hoe, around 12' deep. All the digging is complete in that area, I was very lucky to have found them!"
