🔎 UNIDENTIFIED What is this half cylindrical /half flat 2 holes object I found? It’s got decent weight to it and I’m not sure if it’s copper or not.

If it is copper, it may be a block for a spot welder. I’ve changed a lot of copper tooling on spot welders and some resemble yours. Can’t really see it well in the photos.

1/2 '' double D SHAFT , looks rusty to me , try a magnet to see if it's steel or not.
