I took two of the Brookfield insulator pages from the 1914 Pettingell Andrews electric supplies catalog and roughly corresponded the catalog drawings with the CD drawings in Woody Woodward's " The Glass Insulator in America, 1988 Report". I say roughly because the catalog page photos are not of high enough resolution for me to read the annotated catalog insulator dimensions.

I then corresponded Woody's CD numbers with the 2015 Don Briel "North American Glass Insulators Price Guide". If the CD number was reserved (i.e. not reported yet), such as 222, 223 and 224, I marked the number as "NF" for "Not Found". Sometimes there were Brookfield listings under the CD numbers; other times I made the great leap of faith that the unembossed, no-name, or other embossed insulator was a Brookfield product.

The photo was updated based on early feedback of my posting. Thanks for the help.
