Here's a rare unlisted (only one known) porcelain insulator from France. Has 3 widely spaced pinhole rings, indicating transition phase from threadless to threaded era. Not in any of the WorldWide Porcelain Insulator books nor NIA website. Unmarked. Measures 4 3/4" wide x 5" tall. Looks mint to me.

First email gets this rare and unusual porcelain insulator for only $225 plus shipping. Thanks!
