Damn it took some digging though.
I see I wasn’t smart enough to take any pictures of my little barn find grinder before I tore into it and I could have sworn I did but apparently not. Anyway, when I went and picked it up, it had this funky attachment that came with it and it has been puzzling the shit out of me ever since. I know it has something to do with sharpening shit but I’m also thinking there is a piece missing. There will be more research coming.
With no manufacturer’s name, date, part number or any thing else, it ain’t easy tracking this kind of thing down.
This is about as close as I have gotten and it is pretty brief but at least it gives me some idea.
