Yesterday, I picked up another eBay acquisition at our post office. It was a fuse cut-out I got, simply because it came with the mounting bracket and the fuse intact. I figured it would be pretty much identical to another given to me a couple of years ago by Lou Hall. I was wrong. As you can see in the picture, the new one is larger, has 7 ribs vs. 5 ribs, and the fuse handle also has an extra flange on it. I understand these were used in the late 1920's through the 1940's, perhaps as late as 1950, but as these units are completely unmarked, I have no idea as to who made them.
Do you know anything about these great looking cut-outs, such as who made them, and where were they customarily used. I would appreciate any information. As usual, I am looking to add to my fuse cut-out collection .
