The CD 731 Tillotson in light powder blue aqua which was found in Georgia. This is a better picture than the one which were shown in an earlier post. The picture shows some of the character of this insulator. In this picture, you will immediately notice interesting acid etch marks which circle the dome. I suspect these must have been in the mould for this insulator. Has anyone else ever seen this type of etching on the surface of an insulator. The reverse side of this Tillotson has a nice string of amber and white milk.
