I don't know if there was a sign at the top. This is the first Willard rack that I have come across with the two uprights attached to the top shelf. I thought they might have been for wrapping electrical cables but I could be wrong. It doesn't really need another Willard sign but I suppose that one could have listed all their batteries and different applications. It would be great if someone has a vintage photo of one being used that they could post. Cheers, Don.
