old industrial vintage brown ceramic screw base architectural insulators

Lot of four assorted old and antique industrial and architectural insulators with steel screw bases. These are from an old farm estate and were being used for wiring around the farm and gates and corners on electric fences. This is an unusual and interesting lot as each insulator is different, showcasing the wide variety of electrical insulators made and used across the American countryside.

These insulators are all about 5" long with smears of old paint and a number of chips.
