CD 147 [030] (F-Skirt) PATENTED (R-Skirt) OCT. 8th 1907. Likely a Brookfield product. There is what is either a nail or piece of wire perfectly placed in the spiral groove front and center on the embossed side. I say either a nail or piece of wire because 1 end is pointed like a nail. The other side I can't tell if it is a finishing nail or just had no head on it. There is a small outline of an open bubble about the size of a pencil point profile on the dome mentioned for accuracy. Regardless, I don't consider this damage and would call it mint comfortably.
