Fuse, part, casting, cover?

[Buried Crap NJ]

This also has been sitting around for years and I thought I saw a post that lead me to believe this could be a fuse from the Civil War?
Its also cast but non fearous maybe copper as it has a slight green hue? any help would be great!

Well I have looked at all the post. The gate valve is looking good. I have a problem with the way it would attach to the threads,or even be held in place. There aren't any groves or recesses. The metal is a correct match and it surely looks the part.I am going to electrocute it and see if there any further details. BCNJ

I tried to explain to Dave that it does not attach with threads, it simply floats inside, the dimples holding it in place.

No problem here, I see how it works with the diagram. The valve gate is a 2 piece? Or looks to be and the 2 pieces are secured together.

Yes its 2 piece. Im not exactly sure how its secured. Somehow with the dimples but there is no threaded shank on the piece in question.
