Here's a really cool porcelain insulator with the craziest extended inner skirt pin! (Extends 1 7/8" beyond base!) This very early porcelain insulator has segmented threads (transition period from threadless to threaded= circa 1870-1880) with a mere 3/4" pinhole. Long extended inner pinhole appears to have been glazewelded. Unmarked with snow white glaze.

This unusual insulator has NO cracks or chips! Only light rub marks on crown. Used in South America and maker is unknown but have seen these threads on early French insulators. However, these smaller pinholes are typically made in England (or at least for British capital projects such as British railways). Measures 4 1/4" w x 5 1/2" tall.
