Here's a baby porcelain no-tie insulator found in Belgium. Unmarked but has characteristics consistently found on early Norden Porzellanfabrik insulators made in Copenhagen, Denmark circa 1915-20. In this case, thin fragile snow white porcelain with strong outer mold lines, multiple "XX" in wire groove (and even the base!), small threaded pinhole and rough textured drippy glazed base.

Nearly factory mint condition- (2" tall x 1.45" wide and 3/8" pinhole) has teeny base chips that are glazed over. Tiny glaze crack that doesn't go into porcelain (seen in photo). I believe this was an early dry process insulator which explains the teeny cracking seen inside the porcelain's inner skit.

First email gets this desirable porcelain no-tie insulator for only $50 plus shipping. Thanks
