A while back I had posted some pictures of the porcelain line spacers I had in my collection. I recently came across yet another different one made by Pinco (Porcelain Insulator Corporation). This one has 4 mounting holes and is in a sky gray glaze. It is marked PINCO/L-3234/LIMA, N.Y./PAT 2,921,112. Very unusual configuration. I wonder how many different designs of this did PINCO make? Still looking for and wish to find the pluss shaped one. Now everthing is plastic but that's still a good thing to me.
