Kosters Pottery begin production in the 1880s and started insulator production in the 1930's and after 4-5 years other forms of pottery were phased out. They ceased making insulators in 1977 due to foreign competition from Japan and China. Their insulators are typically ink-stamped "KP" along with the year of manufacture.
