Who made this .576 round ball mold ?

[Sudsy]

Single ball, aluminum (obviously not a Lyman just got it in a Lyman box)
Just picked it up but can't find anything on it. Did a web search using every combination of terms I could think of, nothing.
Because it's aluminum I initially expected it to be a Lee but there's no record that I could find of a Lee mold in this size or with this model number.
An opinion is that it's a Thompson Center that was made in Italy but the markings don't match those, plus I have not found a single record of this size, .576, anywhere from any maker.

Any idea who made this?

Because it is aluminum and doesn't have the machined air escape lines in the face, that looks just like one of the older Thompson Center molds. My older T/C molds looked just like that one.
