Here are images and information for the different style categorizations of glass insulators.

The Consolidated Design numbers (CD numbers) for battery rests are assigned by Kevin Lawless; for threaded pin-types, by N. R. Woodward; for threadless pin-types, by Ray Kligensmith; for threadless blocks, by Ray Klingensmith; for miscellaneous glass, by Marion & Evelyn Milholland; for spools, by N. R. Woodward; and for guy wire strains, by Kevin Lawless.

These descriptions of the ranges of the CD numbers are from the McDougalds' 2003 Glass Insulators Price Guide, and's CD Numbers Explained.
