Here is another interesting company. James R. Kearney Co. were known for there fuse cut-outs and pole line material. They also had some neat wire holders. Pictured L-R Marked Kearney/ 20203-8, next just Kearney on the front, the next piece marked Kearney No 8516 on the front, fourth piece and fifth piece marked Kearney on the front and Pat. 2,155,189. These are really neat with their unique ears on the top. I seen a picture of a white one from the 2018 National show. Wish I had that one. The next piece is marked on the side Kearney No. 8516. This is the Illinois Porcelain Co. 1935 style mold so maybe they made it for kearney. The last piece is marked just Kearney on the front. If you know of or have pictures of different ones I'd be glad to see them. It would be nice to find a catalog as well.
