Here are three uncommon insulators on their original uncommon bracket. There is a small chip in the glaze on the top insulator, as well as a small glaze crack on bottom of the skirt. The middle insulator has a small glaze flake you can see in the picture. The bottom insulator looks OK. There are only a handful of these brackets with U-401s out there.
