I can't seem to imagine it being a cookware item. Interesting that I took a photo (of the entire backside) with Google Lens and the AI overview said, "The item appears to be a cast iron nameplate, possibly from an old piece of machinery or equipment. Based on similar items found online, it could be a nameplate from an E.C. Simmons tool or a similar vintage item." (Insert Twilight Zone theme music here.)
In the world of vintage cast iron cookware, Simmons Hardware is kind of vintage CI adjacent; mostly we only see their Keen Kutter food choppers and waffle irons (probably outsourced from another maker).
